WS4603 - Power Distribution Switch

Datasheet Summary

Description

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.

Features

  • Input voltage range : 2.5~5.5.
  • Main switch RON : 80mΩ @ VIN=5V.
  • Adj. current limit range : 0.4~2A (Typ. ).
  • Current limit accurate : +/-20%.
  • Auto discharge.
  • Reverse block (No “body diode”).
  • Over temperature protection Pin configuration (T.

WS4603 80mΩ,Adjustable Current Limit, Power Distribution Switch WS4603 www.sh-willsemi.com Descriptions 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. Output auto-discharge while the device shutdown made output voltage off quickly. Thermal shutdown function can protect the device and load. SOT-23-5L The WS4603 is available in SOT-23-5L package. Standard product is Pb-free and Halogen-free. Features  Input voltage range : 2.5~5.
