Ultra-Low RDS(ON) Power Distribution Switch with Adjustable Soft Start, Current Limit, and Current Monitoring

Datasheets PDF

General Description

The uP7567 is a small size, ultra-low RDS(ON), load switch with enable control, adjustable soft start, current limit and current monitoring. The uP7567 contains one internal 12mΩ RDS(ON) N-channel MOSFET which supports a continuous current up to 7A.

The switch on/off is controlled by EN pin. In uP7567, a 100Ω discharge MOSFET is built in for quick output discharge when switch is turned off. Additionally, the device features adjustable soft start function, adjustable current limit and over temperature protection. The uP7567 is available in UQFN2x3-17L package.
