TPOWER · LED Drivers · SOT-23-6

TP8151A from TPOWER, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VIN power_in Power supply input that must be decoupled to ground by a capacitor placed right next to the pin, operating at 6V to 55V with an absolute maximum of -0.3V to +60V to GND.
2 CS input Output current sense pin; the sense resistor is connected between VIN and CS, and the VIN-to-CS voltage must stay within -1.0V to +1.0V.
3 DIM input Chip enable and analog/PWM dimming input that turns the power MOSFET off and enters standby below 0.33V, gives full output above 2.5V, and must stay within -0.3V to +6V to GND.
4 GND power_in Signal and power ground for the device, with the DIM, NTC, DRV and VDD pins rated at -0.3V to +6V relative to it.
5 DRV output Gate drive output that connects to the gate of the external power MOSFET, with a stated maximum pull-up current of 450 mA and pull-down current of 620 mA at VGS = 5V.
6 VDD power_out Internal LDO output of nominally 5V that requires a 1uF decoupling capacitor to ground, with a rating of -0.3V to +6V.
