The WS4665 is a single channel load switch that provides configurable rise time to minimize inrush current. The device contains an N-channel MOSFET that can operate over an input voltage range of 0.8V to 5.5V and can support a maximum continuous current of 6A. The switch is controlled by an on/off input (ON), which is capable of interfacing directly with low-voltage control signals. In the WS4665, a 230 Ω on-chip load resistor is added for quick output discharge when switch is turned off.
The WS4665 is available in a small, space-saving 2.00 mm x 2.00 mm 8-pin DFN package. Standard Products are Pb-free and halogen-free.
Applications:
– Ultrabooks™
– Notebooks / Netbooks
– Tablet PCs
– Consumer Electronics
– Set-top Boxes / Residential Gateways
– Telecom Systems
