TPNTJD1155LT1G from TECH PUBLIC, in a SOT-363. 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 | S1 | power_in | Source of level-shift MOSFET Q1, connected to ground (GND) in the typical application circuit. |
| 2 | D2 | power_out | Drain of P-channel load switch MOSFET Q2, tied with pin 3 and used as the switched output (VOUT) with continuous load current up to 1.3 A. |
| 3 | D2 | power_out | Drain of P-channel load switch MOSFET Q2, tied with pin 2 and used as the switched output (VOUT) with pulsed load current up to 3.9 A. |
| 4 | S2 | power_in | Source of load switch MOSFET Q2, connected to the input supply VIN (1.8 to 8.0 V operating range, 8 V maximum). |
| 5 | G1 | input | Gate of level-shift MOSFET Q1, the ON/OFF control input (1.5 to 8.0 V range, ESD protected to 2 kV HBM). |
| 6 | G2/D1 | passive | Common node of Q2 gate and Q1 drain, pulled up to VIN through resistor R1 (typically 10 kΩ to 1 MΩ) in the application circuit. |
