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. |
