WS4611 Datasheet (WillSEMI) - Power Distribution Switch

WS4611, Power Distribution Switch

The WS4611 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 WS4611 is also integrated reverse protection function to eliminate a
