IW673-20 from RENESAS, 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 | DRAIN | input | Synchronous rectifier MOSFET drain voltage sensing and the Pulse Linear Regulator (PLR) input, with absolute maximum voltage of -1.5 to 60 V. |
| 2 | SOURCE | input | Synchronous rectifier MOSFET source voltage sensing input, with absolute maximum voltage of -0.6 to 1 V. |
| 3 | OUT | output | Synchronous rectifier MOSFET driver output, with gate peak output current of ±3 A absolute maximum. |
| 4 | GND | power_in | Ground. |
| 5 | VCC | power_in | Output of internal LDO and PLR providing bias voltage for the internal logic circuit and the MOSFET driver; connect this pin to a capacitor (absolute maximum -0.6 to 6 V). |
| 6 | VIN | power_in | Input of internal LDO and system output voltage sensing circuit, connected to adapter/charger output; the LDO clamps VCC at 5V when VIN > 5V and VIN also feeds the PLR enable and SR enable comparators (absolute maximum -0.3 to 33 V). |
