General Description

s 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 any reverse current flow across the switch when the device is off.
