The WS4667E is a small, ultra-low Ron, single channel load switch with controlled turn on. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8V to 3.5V and supports a maximum continuous current of 4.5A.

This device is suitable for driving processor power rails with very strict voltage dropout tolerances. Quick rise time of the device allows for power rails to come up quickly when the device is enabled, thereby reducing response time for power distribution. The ON terminal can be directly connected with the low-voltage control signals generated by microcontrollers or low-voltage discrete logic circuit.

The WS4667E is available in SOT23-6L package. Standard product is Pb-free and Halogen-free.

Applications:
– Ultrabooks™
– Notebooks / Netbooks
– Tablet PCs
– Consumer Electronics
– Set-Top Boxes / Residential Gateways
– Telecom Systems

Input Voltage Range: 0.8V to 3.5V
