SI1865DDL 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 N-channel Q1, connected to the optional slew-rate control resistor R2 (typically 0 to 100kΩ) to ground. |
| 2 | D2 | passive | Drain of P-channel load switch Q2 (load output), tied to pin 3, with VDS rated at -20 V and continuous load current of 1.3 A. |
| 3 | D2 | passive | Drain of P-channel load switch Q2 (load output), tied to pin 2, with VDS rated at -20 V and continuous load current of 1.3 A. |
| 4 | S2 | power_in | Source of Q2 and the input voltage (VIN) pin, with input voltage range up to 20 V. |
| 5 | ON/OFF | input | Gate of level-shift transistor Q1 that turns the load switch on and off, with an on/off voltage range of 8 V maximum and ESD of 2 kV HBM. |
| 6 | R1,C1 | passive | Connection of Q1 drain to Q2 gate, used for the pull-up resistor R1 (typically 10kΩ to 1MΩ) and optional slew-rate capacitor C1 (typically 1000pF). |
