WS4601
WS4601
80mΩ, Current Limited, Power Distribution Switch
www.sh-willsemi.com
Descriptions
The WS4601 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 WS4601 is also integrated reverse protection
function to eliminate any reverse current flow across
the switch when the device is off. Output
auto-discharge while the device shutdown made
output voltage off quickly. Thermal shutdown function
can protect the device and load.
The WS4601 is available in SOT-23-5L package.
Standard product is Pb-free and Halogen-free.
