TPSI1869DH-T1-E3 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 | R2 | passive | Source of level-shift MOSFET Q1 (R2 node), connected to the optional external slew-rate resistor R2 (typical 0 to 100kΩ) that goes to GND. |
| 2 | D2 | passive | Drain of P-channel load switch Q2 (VOUT side, tied with pins 3), rated VDS -20 V with 1.3 A continuous load current. |
| 3 | D2 | passive | Drain of P-channel load switch Q2 (VOUT side, tied with pin 2), rated VDS -20 V with 1.3 A continuous load current. |
| 4 | S2 | power_in | Source of load switch Q2, the VIN input, with input voltage range up to 20 V. |
| 5 | ON/OFF | input | Gate control input of level-shift MOSFET Q1 that turns the switch on and off, with On/Off voltage range of 8 V maximum (1.5 V used as the on level in test conditions) and 2 kV HBM ESD. |
| 6 | R1,C1 | passive | Node joining the Q1 drain to the gate of Q2, where the optional pull-up resistor R1 (typical 10kΩ to 1MΩ) and slew-rate capacitor C1 (typical 1000pF) connect. |
