The eight non-Darlingtonoutputs of each driver can continuously and simultaneously sink load currents of 100 mA at ambient temperatures of up to +75°C.The eight-channel driver’s active-low inputs can be driven directly from TTL, Schottky TTL, DTL, 5 to 16 V CMOS, and NMOS logic.All input connections are on one side of the package, output connec-tions on the other, for simplified printed wiring board layouts.These drivers are packaged in plastic DlPs (suffix A) or surface-mountable wide-body SOlCs (suffix LW), and are rated for operation over the temperature range of -20°C to +85°C. The A2595SLW is also available for operation to -40°C. To order, change the suffix from ‘SLW’ to ‘ELW’.FEATURESI Non-Inverting Function(Input Low = Output ON)I 200 mA Current RatingI 100 mA Continuous and Simultaneous(All outputs) to +85°C I Low Saturation Voltage I TTL, CMOS, NMOS Compatible I Efficient Input/Output Pin Format I DIP or SOIC PackagingUDN2595A25958-CHANNELSATURATED SINK DRIVER115 Northeast Cutoff, Box 15036Worcester, Massachusetts 01615-0036 (508) 853-500050751001251502.50.5A L L O W AB L E P AC K A G E P O W E RD I S S I P A T I O N I N W A T T SAMBIENT TEMPERATURE IN °C2.01.51.025Dwg.

全极低功耗霍尔开关SS259使用手册
Packages Features and Benefits– Operation down to 2.5V– Micropower consumption for batterypowered applications– High sensitivity for direct reed switchreplacement applications– Omnipolar, output switches with absolutevalue of North or South pole from magnet 3 pin SOT23 (suffix SO) 3 pin SIP (suffix UA)Functional Block Diagram Application Examples–Solid-state switch– Handheld Wireless Handset Awake Switch – Lid close sensor for battery powered devices –Magnet proximity sensor for reed switch replacement in low duty cycle applicationsGeneral Description:The SS259 Omnipolar Hall effect sensor IC is fabricated from mixed signal CMOS technology. It incorporates advanced chopper-stabilization techniques to provide accurate and stable magnetic switch points.The circuit design provides an internally controlled clocking mechanism to cycle power to the Hall element and analog signal processing circuits. This serves to place the high current-consuming portions of the circuit into a “Sleep” mode. Periodically the device is “Awakened” by this internal logic and the magnetic flux from the Hall element is evaluated against the predefined thresholds. If the flux density is above or below the B OP /B RP thresholds then the output transistor is driven to change states accordingly. While in the “Sleep” cycle the output transistor is latched in its previous state. The design has been optimized for service in applications requiring extended operating lifetime in battery powered systems.The output transistor of the SS259 will be latched on (B OP ) in the presence of a sufficiently strong South or North magnetic field facing the marked side of the package. The output will be latched off (B RP ) in the absence of a magnetic field.Typical Application CircuitSEC's pole-independent sensing technique allows for operation with either a north pole or south pole magnet orientation, enhancing the manufacturability of the device. The state-of-the-art technology provides the same output polarity for either pole face.It is strongly recommended that an external bypass be connected (in close proximity to the Hall sensor) between the supply and ground of the device to reduce both external noise and noise generated by the chopper-stabilization technique. This is especially true due to the relatively high impedance of battery supplies.Internal Timing CircuitPin Definitions and DescriptionsSOT Pin №SIP Pin №Name Type Function1 1 VDD Supply Supply Voltage pin2 3 OUT Output Open Drain Output pinGroundpin3 2 GNDGroundTable 1: Pin definitions and descriptionsAbsolute Maximum RatingsParameter Symbol Value UnitsSupply Voltage (operating) V DD 6 VmASupply Current I DD 5Output Voltage V OUT 6 VOutput Current I OUT 5mA85°CtoOperating Temperature Range T A -40150°CStorage Temperature Range T S -50toESD Sensitivity - 4000 VTable 2: Absolute maximum ratingsExceeding the absolute maximum ratings may cause permanent damage.

CMOS makes this advanced technique possible. The CMOS chip is also much smaller than a bipolar chip, allowing very sophisticated circuitry to be placed in less space. The small chip size also contributes to lower physical stress and less power consumption.Installation CommentsConsider temperature coefficients of Hall IC and magnetic, as well as air gap and life time variations.

电子管基础设计和结构说明书
Tube TopicsSection 1: Basic Tube DesignA vacuum tube consists of a vacuum envelope containing various electronic ele-ments used to emit, control, and collect a flow of electrons. A filament or cathode provides a source of electron emission. Up to three grids; the control, screen, and suppressor grids control the flow of electrons within the tube and a plate or anode collects the electron flow. Electrical energy that is not transferred to the load is converted to heat at the anode.Figure 1 shows the interior elements of a tetrode. These elements are mounted and aligned parallel and concentric with each other but are electrically isolated, as shown in Figure 2. In the example device, each bar and spiral of thescreen grid is “hidden” from the filament by a corresponding control grid bar.(a) (b) (c)Figure 1. The interior of a tetrode: (a) mesh filament, (b) control grid (c) screen gridFigure 2. Interior assembly of a power tetrode.1.1 Electron Emitter TypesThe electron emitters in vacuum tubes are either directly heated or indirectly heated. The tube types we are concerned with in this booklet are directly heated, filamentary tubes.Operating techniques that are proper for filamentary tubes are not necessarily correct for tubes with indirectly heated cathode emitters. In particular, the opera-tion of cathode types at reduced heater voltage can be destructive to the tube.Filament DesignsDirectly heated tubes have either spiral, parallel bar, hairpin, or mesh filament structures. The spiral filament structure consists of one or two strands of wire that are spiral wrapped around a central support rod. They are found in older, lower power designs. Spiral filaments are subject to sagging and shorting between the turns. As illustrated in Figure 3, the filament in (a) is normal while the filament shown in (b) has sagged because of excess filament voltage. These particular tubes operate inverted. Note the shorted turns at the top of (b).(a) (b)Figure 3. 5762/7C24 spiral filaments: (a) normal filament, (b) abnormal filamentThe hairpin structure is found in many power tubes currently installed. It con-sists of a number of parallel elements bent into the shape of a hairpin (thus the name). The current path is up one leg, across the top, and down the adjacent leg. Hairpin filament support structures have built in spring compensation for thermal expansion of the filament (Figure 4.). These filament structures can have all voltages applied without filament warm-up. Tuning will drift slightly because of relative movement of the tube elements as they reach thermal equilibrium, but there is no danger of shorting. Some tube designs require surge current limitation for the filament when initially turned on. This protection should be provided for by the equipment manufacturer and should not be bypassed.Figure 4. The hairpin filament structureFigure 5. Mesh filament structureMesh filaments are composed of filament wires woven to form a basket weave filament structure. (Figure 5.) The wire joints are spotwelded or diffusion bonded at the intersections. Mesh filaments are being designed into most new tube designs on the theory that a mesh filament permits a denser, more closely spaced structure. This allows higher stage gain, increased efficiency and higher frequency operation.The mesh structure relies on thermal expansion of the ridged upper filament support structure to compensate for thermal expansion of the filament. The current path is from the base, up through mesh filament, across top, and down through the center support rod Mesh filaments require slower warm-up as the thin, low mass filament wires come to temperature immediately as voltage is applied. As they heat, they expand, and until the more massive and slower to heat support structures reach their operating temperature to compensate for this expansion, the filament wires warp in and out. A warped filament greatly increases the possibility of a thermal grid-to-filament short circuit. Common precautions for filament operation are detailed in Section 2.5 (“Filament Voltage”). Attention to filament voltage is vital to long life and stable operation of filamentary tubes.1.2 GridsGrid elements are generally formed of wires spotwelded together to form a circular structure that completely surrounds the emitting surface of the filament. The grid controls the flow of electrons from the filament. Grids are coated withvarious materials compounded to manage the emission of electrons from thegrid. If emission of electrons from the grid is uncontrolled, it can result in high distortion or a destructive runaway effect in the tube.1.3 AnodeAnodes are copper cylinders or drawn cups that collect the flow of electrons within a tube. They have air cooling fins, vapor cooling surfaces, or water cooling jackets brazed to their exterior in order to remove the heat generated by the power not transferred to the load.PlatingThe external metal parts of tubes are plated with nickel or silver. Tubes that go into sockets are normally silver plated. The soft silver provides a better contact interface than the much harder nickel; it deforms slightly under contact pressure providing greater contact area. Silver plating has a dull, whitish cast, whereas nickel has a hard metallic appearance.Nickel is resistant to discoloration resulting from heat at normal tube operating temperatures, while silver will tarnish easily. Often, the heat patterns on silver plated tubes are helpful in problem analysis. If a nickel plated tube shows any sign of heat discoloration, a significant cooling or operational problem exists. Nickel will not discolor until it reaches a temperature much higher than a tube will reach under normal conditions. If a nickel plated tube discolors, abnormal operating conditions are present.SafetyPower tubes and the equipment they are installed in have electrical voltages present that can be lethal. The access panels to all high voltage cabinets should be installed. All interlocks should be operating and never bypassed. High voltage cabinets should be equipped with a shorting bar, which should be directly grounded. The bar is used to ground all high voltage areas before reaching into them to work on or inspect any components.Proper equipment design requires that all high voltage circuits have bleeder resistors to bleed off any residual charge to ground when the equipment is turned off. Full discharge by these bleeder circuits may take several seconds.1.4 SocketsPrior to installing a tube, it is wise to inspect the socket to determine if there are any broken pieces of fingerstock. Broken pieces of fingerstock can fall into the equipment causing shorts and other damage. They should be located and removed prior to installation of the tube. Individual finger contacts can break off on occasion and as long as they are located and removed, the socket ring does not require replacement. If more than 20 percent of fingerstock are broken off, the contact ring should be replaced. Consecutive gaps around the tube can cause improper tuning, instability, and lead to premature failure.Repair kits are available for most sockets from manufacturers. This method is far cheaper than replacing the entire socket. ECONCO is happy to advise a tube user as to where specific socket replacement parts can be obtained.Socket ProblemsLoose contact on a tube socket will always lead to problems. Some socket designs have a wire-wound spring encircling the outside circumference of the fingerstock to increase individual finger contact pressure. These should be replaced if they break or lose tension. Adequate contact pressure is vital for proper operation and long life. Some sockets have stops that are set so that the tube has the grid contacts in the middle of the contact area when fully inserted. This positioning can be checked by inserting and then removing a new tube. The scratch marks on the grid contacts will show the position of the tube relative to the socket contacts.Figure 6 shows a burned and melted grid ring on an industrial triode. This fail-ure was caused by poor contact between the grid ring and the socket.Figure 6. An industrial triode thatfailed because of socketingproblems.Tube InsertionGently rock and slightly rotate the tube as it is being inserted into the socket. This helps avoid bending and breaking of fingerstock. Be sure to apply sufficient force to seat the tube all the way into the socket. Never use a lever or hammer on the tube to set it into the socket. Manual pressure should be adequate. An intermediate point is reached when the grid contact fingerstock slides up the tube sides and first contacts the connection areas. It is important to be sure the tube is fully inserted in the socket beyond this initial point of resistance.Tubes Without SocketsMany industrial tubes and tubes used in medium-wave service are not socketed but are installed into the equipment by bolted or clamped connections. Clamped anode connections made of stainless steel should have some method of strain relief to avoid excess pressure collapsing the anode of the tube as it heats up inoperation. Stainless steel has a much lower coefficient of thermal expansion than copper.All bolted or screwed connections should be tight. It is important to check that the clamps are snug, providing good electrical contact around the entire circumfer-ence of the contact area. Because of the radio frequency fields present, all clamps and bolts should be made from non-magnetic materials. Copper, brass, or non-magnetic Series 300 stainless steel fasteners are preferred. Stainless steel is not a good conductor of electricity, and while it is used for clamping, it should not be part of the current path.。
