AH1815低敏感度微电流双极性磁场开关数据手册说明书
LOW SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCHDescriptionThe AH1815 is a low-sensitivity, micro-power Omnipolar Hall effect switch IC, designed for portable and battery powered consumer equipment for home appliance and industrial applications such as smart-meter magnetic-tamper detection. Based on two sensitive Hall effect plates and a chopper-stabilized architecture, the AH1815 provides a reliable solution over the whole operating range. To support portable and battery powered equipment, the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24µW with a supply of 3V.The single open drain output can switch on with either a north or south pole of sufficient strength. When the magnetic flux density (B) perpendicular to the package is larger than operating point (Bop) the output is switched on (pulled low). The output is turned off when B becomes lower than the releasing point (Brp). The output will remain off when there is no magnetic field.Features∙ Omnipolar (North or South pole) Operation ∙ Low Sensitivity∙ Single Open Drain Output ∙ Micropower Operation∙ 2.5V to 5.5V Operating Range∙Chopper Stabilized Design Provides Superior Temperature Stability Minimal Switch Point Drift Enhanced Immunity to Stress ∙ Good RF Noise Immunity∙ -40°C to +125°C Operating Temperature ∙ ESD (HBM) > 6KV∙ Small Low Profile SOT553 and Industry Standard SC59 and SIP-3 Packages∙ Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) ∙ Halogen and Antimony Free. “Green” Device (Note 3)Pin Assignments(Top View)132OUTPUTGND V DDSC59(Top View)NC OUTPUTV DDGND NCSOT553(Front View)1.V DD2.GND3.OUTPUTSIP-3Applications∙ Doors, Lids, Covers and Tray Position Detect Switches ∙ Display Switch for Portable PCs and Tablets ∙ On/Off Switch for PDAs and Digital Cameras∙ Liquid Level Detection for Coffee Machines ∙ Smart Meters∙Position, Proximity and Level Detection Contactless Switch in Battery Powered Consumer, Home Appliances and Industrial ApplicationsNotes: 1.

Both MOSFETs have integrated back to back gate-source Zener diode clamps and guaranteed R DS(ON) ratings down to 4.0V gate drive allowing them to be driven directly with standard 5.0V CMOS logic.These low threshold enhancement-mode (normally-off) transistors utilize an advanced vertical DMOS structure and Supertex’s well-proven silicon-gate manufacturing process. This combination produces devices with the power handling capabilities of bipolar transistors and with the high input impedance and positive temperature coefficient inherent in MOS devices. Characteristic of all MOS structures, these devices are free from thermal runaway and thermally-induced secondary breakdown.Supertex’s vertical DMOS FETs are ideally suitedto a wide range of switching and amplifying applications where very low threshold voltage, high breakdown voltage, high input impedance, low input capacitance, and fast switching speeds are desired.N- and P-ChannelEnhancement-Mode Dual MOSFET-G indicates package is RoHS compliant (‘Green’)GP SP GN SNDP DP DN DNYY = Year Sealed WW = Week Sealed L = Lot Number= “Green” Packaging 8-Lead SOIC (TG)(top view)Absolute Maximum Ratings are those values beyond which damage to the device may occur.
