WS4611
WS4611
80mΩ, Current Limited, Power Distribution Switch
www.sh-willsemi.com
Descriptions
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 any reverse current flow across
the switch when the device is off. Thermal shutdown
function can protect the device and load. The output
auto-discharge function is disabled in WS4611.
SOT-23-5L
The WS4611 is available in SOT-23-5L package.
Standard product is Pb-free and Halogen-free.
