WS4603 Datasheet (WillSEMI) - Power Distribution Switch

WS4603, Power Distribution Switch

The WS4603 is high-side switch with ultra-low ON resistance P-MOSFET.

Integrated current-limit function can limit inrush current for heave capacitive load, over load current, and short-circuit current to protect power source.

The WS4603 is also integrated reverse protection function to eliminate an
