IW662-02-SO8 from Dialog Semiconductor, in a SOIC-8. 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 Pulse Linear Regulator (PLR) input, with DRAIN pin voltage rated -1.5 V to 100 V and not below -0.6 V for more than 500 ns. |
| 2 | DIS | output | Discharging circuit output used for fast discharging of the output capacitor, with DIS pin voltage rated at 30 V maximum. |
| 3 | D- | input | USB D- signal input, with D- pin voltage rated -0.3 V to 7 V. |
| 4 | D+ | input | USB D+ signal input, with D+ pin voltage rated -0.3 V to 7 V. |
| 5 | OUT | output | Synchronous rectifier MOSFET gate driver output, with OUT voltage limited to -0.6 V to VCC + 0.6 V and gate peak output current rated ±3 A. |
| 6 | GND | power_in | Ground reference for the controller. |
| 7 | VCC | power_out | LDO and PLR output that must be connected to a capacitor, with VCC pin voltage rated -0.6 V to 6 V and continuous supply current rated 15 mA at VCC = 5.5 V. |
| 8 | VIN | power_in | Input of the internal LDO and output voltage sensing circuit, connected to the adapter/charger output for bias; the internal LDO clamps VCC at 5 V when VIN > 5 V, with VIN rated -0.3 V to 33 V. |
