# TPM1869C6

**TECH PUBLIC** · Power Distribution Switches · SOT-363-6

TPM1869C6 from TECH PUBLIC, in a SOT-363-6. 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 | R2 | passive | Source of Q1 and connection for the optional slew-rate control resistor R2 (typical 0 to 100kΩ) to ground. |
| 2 | D2 | passive | Drain of Q2 (load/output side, VOUT in the application circuit), tied to pin 3; drain-source voltage of Q2 is rated -20 V. |
| 3 | D2 | passive | Drain of Q2 (load/output side, VOUT in the application circuit), tied to pin 2; drain-source voltage of Q2 is rated -20 V. |
| 4 | S2 | power_in | Source of Q2 and input supply (VIN) of the load switch, with input voltage range rated 20 V. |
| 5 | ON/OFF | input | Gate control input of Q1 that switches the load on and off, with on/off voltage range of 8 V maximum and 2 kV HBM ESD rating. |
| 6 | R1.C1 | passive | Common node of Q1 drain and Q2 gate, where the pull-up resistor R1 (typical 10kΩ to 1MΩ) and optional slew-rate capacitor C1 (typical 1000pF) connect. |
