WS4601E-5

WILLSEMI Will Semicon · Power Distribution Switches · SOT-23-5L

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.
