# FDC6331L-TP

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

FDC6331L-TP 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 | R2 | passive | Source of control FET Q1, returned to ground in the application circuit, with optional slew-rate control resistor R2 (typical 0 to 50kΩ). |
| 2 | Vout,C1 | power_out | Load switch output (drain D2 of Q2, tied with pin 3) with optional slew-rate capacitor C1 (typical 1000pF). |
| 3 | Vout,C1 | power_out | Load switch output (drain D2 of Q2, tied with pin 2) with optional slew-rate capacitor C1 (typical 1000pF). |
| 4 | Vin,R1 | power_in | Switch input (source S2 of Q2), absolute maximum input voltage ±8V, with pull-up resistor R1 (typical 20kΩ to 1MΩ) to the gate node. |
| 5 | ON/OFF | input | Gate control input of Q1 that turns the load switch on or off, absolute maximum -0.5 to 8V. |
| 6 | R1,C1 | passive | Internal node joining Q1 drain and Q2 gate, connected to pull-up resistor R1 and slew-rate capacitor C1. |
