WS4601E-5 from WILLSEMI Will Semicon, in a SOT-23-5L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OUT | power_out | Output of high-side power switch with maximum continuous current 1.0A at 80mΩ ON-resistance (VIN=5V) and 0.7A short-circuit current limit. |
| 2 | GND | power_in | Ground reference. |
| 3 | FLG | tri_state | Open-drain fault flag output, active low, asserted with 8ms typical delay when over-current (1.5A threshold) or over-temperature (160°C threshold) condition occurs. |
| 4 | EN | input | Enable input, active high with logic thresholds VIL=0.4V and VIH=1.6V (at VIN=5V); drive low to enter shutdown mode with quiescent current <1µA. |
| 5 | IN | power_in | Power supply input, rated 2.5V to 5.5V with under-voltage lockout at 2.2V typical, quiescent current 48-60µA. |
