# TPNTGD1100LT1G

**TECH PUBLIC** · Power Distribution Switches · SOT-23-6

TPNTGD1100LT1G from TECH PUBLIC, 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 | S1 | passive | Source of Q1 (level-shift N-channel), shown as R2 in the circuit diagram, where an optional 0 to 100kΩ slew-rate control resistor connects to ground. |
| 2 | D2 | passive | Drain of Q2 (load switch output, VOUT), tied internally to pin 3 and carrying up to ±3.5 A continuous load current. |
| 3 | D2 | passive | Drain of Q2 (load switch output, VOUT), tied internally to pin 2 and carrying up to ±3.5 A continuous load current. |
| 4 | S2 | power_in | Source of Q2 (load switch input, VIN), rated 1.8 V to 8 V input with an 8 V absolute maximum. |
| 5 | G1 | input | ON/OFF gate input of Q1 with 1.5 V to 8 V logic level control, 8 V absolute maximum and 2000 V HBM ESD protection. |
| 6 | D1/G2 | passive | Common drain of Q1 and gate of Q2 (R1, C1 node), where an optional pull-up resistor R1 (typically 10kΩ to 1MΩ) and slew-rate capacitor C1 (typically 1000pF) connect. |
