EUM6861 Datasheet

EUM6861 Datasheet

18VDESCRIPTIONEUM6861/A/B is a fan motor driver for the single coil brushless DC motor. With its high efficient direct PWM control mode, EUM6861/A/B controls the speed of brushless DC motor with a built in HALL IC interface. EUM6861/A/B is suitable to drive variable speed motors for personal computer’s power supply radiation fans and CPU coolers.EUM6861/A/B integrates PWM fan speed control, minimum speed mode, soft start, fan tachometer, lock protection, auto restart and Hall Bias functions. PWM mode controls fan speed in low noise and low vibration ways by adjusting RCTL voltage. EUM6861/A/B can set minimum fan speed by presetting RMIN voltage. With soft start function, EUM6861/A/B can drive motor from slow speed to fast speed in a settable time by setting the external capacitor between SS and GND. If a fan motor is stalled by the external force or obstacles, overdrive current may incur coil overheat and burning. To prevent motor from overheating, the lock protection circuit shuts down the internal power devices for a few seconds after the motor lock is detected. Then the auto restart circuit resumes to power up the internal power devices. If the lock persists, EUM6861/A/B shuts off power devices for a few seconds. The lock protection delay time is externally programmable by a capacitor. EUM6861 has built in motor rotation speed feedback (FG) output, motor rotation detection (RD) output and Hall sensor bias output.Application Circuit z Built in 18V Full-wave Motor Driver for Fan Motorz Built in Input Surge Protection, No Zener Diode Needz External Programmable Soft Start and Soft Restart Functionz Wide Input Range 3V~18V z PWM Fan Speed Controlz Programmable Minimum Fan Speed z Built in Soft Switching Function z Built in Hall Biasz Lock Protection and Auto Restartz Fan Rotation Speed Feedback FG Output (EUM6861/B)z Fan Rotation Detection RD Output (EUM6861/A)z Thermal Shutdown Protectionz Available in TSSOP-16 and TDFN-14 Packages zRoHS Compliant and 100% Lead (Pb)-Free Halogen-FreeAPPLICATIONSz Personal Computer’s Power Supply Radiation Fans and CPU CoolersFigure 1.

Hall Sensor InputsHall signal input terminals (H+、H-)Figure 7. Hall Sensor Input Voltage RangeSet Hall sensor input signal range 0.2V to 3V by adjusting the Hall input level setting resistor R1. In the case of long board wiring pattern from hall element to hall signal input terminal, connect a capacitor between IN+ and IN- to avoid noise. The amplitude of Hall input signal is recommended to be 60mV or higher due to the Hall input amplifier 20mV hysteresis. The Hall bias is 1.2V.VCC Bypass CapacitorConnect a ceramic capacitor 0.47μF or more between VCC and GND to absorb kick back voltage resulting from the high side re-circulation current.GND and PGND LineGND is connected to internal analog control circuits, and PGND is connected to power devices. Connect GND to PGND at only one place on the PCB board. PWM Oscillator FrequencyThe PWM OSC frequency is programmed by the CP capacitor. A 100pF CP sets frequency 25 KHz. The PWM OSC ramp CPWM swings between 2V to 3.55V. PWM Control Speed ModePWM control mode works by comparing the voltage of RCTL and CPWM. When RCTL is low, one side upper power device and the other side lower side power device are turned on to charge the motor coil. When RCTL is high, the upper side power device is turned off. The motor coil current is re-circulated between lower side power devices. The lower RCTL is, the bigger the output duty is. Big coil current makes motor run fast. FG output feedbacks motor rotational speed. The motor coil is charged all the time and motor speed becomes full speed when RCTL voltage is lower than 2V.Soft Start TimeConnect a capacitor between SS and GND to set soft start time. EUM6861/A/B drives a motor from slow speed to fast speed during soft start time which is set by the external capacitor between SS and GND. Floating SS pin if soft start function is not used. If motor start current is too big, please increase capacitor between SS and GND to make start time longer and start current smaller. If motor start current is too small to run, please decrease capacitor between SS and GND to make start time shorter and start current bigger.Minimum Speed ModeMinimum speed of motor is set by the RMIN voltage. When RCTL voltage is higher than RMIN voltage, the lowest duty is set by comparing RMIN and PWM oscillator ramp CPWM voltage. When minimum speed mode function is not used, connect RMIN to RCTL. If RMIN pin is connected to RCTL and the RCTL/RMIN voltage is above 3.6V, EUM6861/A/B PWM duty cycle is 0% and motor stops.Lock Protection and Auto RestartWhen the motor is locked, the EUM6861/A/B outputs will be disabled by the lock protection function. After a few seconds, the auto restart circuit will restart the motor. If the motor lockup persists, the lock protection will keep EUM6861/A/B outputs off until the lock removes. Rotation detection output RD pin is open-drain output, and RD is internally pulled down during rotation mode. When motor lock is detected, RD pin becomes high impedance. See Figure 8.Figure 8.

DFN3030-10L (Top View)Figure 1, Pin Assignments of OCP8111General DescriptionThe OCP8111 is current-regulated charge pump ideal for powering high brightness LEDs for cameraflash applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The OCP8111 automatically switches modes between step-up and step-down ensuring that LED current does not depend on the forward voltage. Itswitches at 1.8MHz, allowing the use of tiny components. The supply voltage ranges from 2.7V to 5.5V and is ideally suited for all applications powered by a single Li_Ion battery cell or three to four NiCd, NiMH, or Alkaline battery cells.The OCP8111 also features a very low shutdown current (less than 1uA), an automatic soft-start mode tolimit inrush current, as well as over current, over voltage and over temperature shutdown control. A Low current sense reference voltage (50mV) allows the user of small 0603 current sensing resistors. The OCP8111 is offered in Green 10-pin DFNpackage and is specified over an ambient temperature range of -40˚C to 85˚C.

The OCP8111 has two modes of operation which are pin-selectable for either Flash or Torch. Flash mode is usually used with a pulse of about 200 to 300 milliseconds to generate a high intensity Flash. Torch can be used continuously at a lower output current than Flash and is often used for several seconds in a digital still camera “movie” mode.The OCP8111 also has two modes of operation to control the output current: the 1 X mode and 2X mode. Operation begins after the enable pin EN receives a logic high, then OCP8111 goes through a soft-start mode designed to reduce inrush current. The OCP8111 starts in the 1X mode, which acts like a linear regulator to control the output current by continuously monitoring the feedback pin FB. In 1 X mode, if the OCP8111 auto detects a dropout condition, which is when the FB pin is below the regulation point for more than 64 cycles of the internal clock, the OCP8111 automatically switches to the 2X mode. The OCP8111 remains in the 2X mode until one of three things happens:1) The enable pin EN has been toggled2) The Flash pin has changed from high to low 3) VIN is cycledThe 2X mode is the charge pump mode where the output can be pumped as high as two times the input voltage, provided the output does not exceed the maximum voltage for the OCP8111, which is internally limited to about 5.1V. In the 2X mode, as in the 1 X mode, the output current is regulated by the voltage at the FB pin.In the Torch mode, (Flash = GND) the Flash pin is set to logic low and the OCP8111 FB pin regulates to 50mV output:V FB = 50mV (Torch Mode)When in Flash mode, (Flash = VIN), the FB regulation voltage is set by the resistor R SET connected between the R SET pin and SGND and the equation:5*14SETFB R uA V =(Flash Mode)Where 14μA is an internal regulated current and 5 is an internal factor used to scale the V SET voltage to the V FB voltage. Typical values of RSET are 140K Ω to 35K Ω for a range of V FB = 400mV to 100mV in Flash mode.The output current is then set in either Flash or Torch mode by the equation:SENSEOUT R V I FB=FLASH Timeout Protection:Due to the high currents typically available in Flash mode, it is necessary to protect the white LED from damage if left on too long. The OCP8111 has a timeout in Flash mode of about 1.2seconds to 3.8seconds after which it will shut down operation. Operation will not begin again in Flash mode until the Enable pin or Flash pin have been set Low and then High again.Over-voltage Protection:The OCP8111 has over voltage protection. If the output voltage rises above the 5.1V threshold, the over voltage protection shuts off all of the output switches to prevent the output voltage from rising further. When the output decreases below 5.1V, the device resumes normal operation.Over-current Protection: The over current protection circuitry monitors the average current out of the VOUT pin. If the average output current exceeds approximately 1.6 Amps, then the over current protection circuitry shuts off the output switches to protect the chip.Brightness Control using PWM:Dimming control can be achieved by applying a PWM control signal to the EN pin. The brightness of the white LEDs is controlled by increasing and decreasing the duty cycle of the PWM signal. While the operating frequency range of the PWM control is from 60Hz to 700Hz, the recommended maximum brightness frequency range of the PWM signal is from 60Hz to 200Hz. A repetition rate of at least 60Hz is required to prevent flicker.Over-temperature Protection:When the temperature of the OCP8111 rises above 145℃, the over temperature protection circuitry turns off the output switches to prevent damage to the device. If the temperature drops back down below 135 degrees Celsius, the part automatically recovers and executes a soft start cycle.Ordering InformationPart NumberDriver CapabilityPackage TypePackage Qty Temperature Eco Plan Lead OCP8111VAD 1.0A DFN3030-10L13-in reel 3000pcs/reel-40~85℃GreenCuMarking InformationDFN3030-10LOCP8111XXX Package :V:DFN3030-10L Packing :A:Tape&Reel Temperature Grade : D: -40°C~85°C Part NumberPin 1 SignLogoPackage Information DFN3030-10L:SymbolDimensions In Millimeters Dimensions In Inches Min.
