SI3865DDV from TECH PUBLIC, in a SOT23-6L. 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 the Q1 level-shift MOSFET, returned to GND directly or through the optional slew-rate-control resistor R2 (typical 0 to 50kΩ). |
| 2 | D2 | power_out | Drain of P-channel switch Q2 (VOUT load output, tied to pin 3), rated 2.8A continuous and 6A pulsed load current. |
| 3 | D2 | power_out | Drain of P-channel switch Q2 (VOUT load output, tied to pin 2), rated 2.8A continuous and 6A pulsed load current. |
| 4 | S2 | power_in | Source of P-channel switch Q2 and the VIN input, operating range 1.5V to 12V. |
| 5 | ON/OFF | input | Logic-level control input to the gate of Q1 with 2000V HBM ESD protection, 1.8V to 8V logic level, absolute maximum 8V. |
| 6 | R1, C1 | passive | Gate node of Q2 and drain of Q1, where pull-up resistor R1 (typical 20kΩ to 1MΩ) to VIN and optional slew-rate capacitor C1 (typical 1000pF) connect. |
