产品概述 返回TOP
The CXUS7734 CXUS7734QB is an ultra-low on-resistance, dual powerdistribution switch with external soft start control. It integrates two N-channel MOSFETs that can deliver 6A continuous load current each. The device integrates over-temperature protection. The over temperature protection function shuts down the Nchannel MOSFET power switch when the junction temperature rises beyond 160oC and will automatically turns on the power switch when the temperature drops by 40oC. The device is available in lead free TDFN2x3-14A packages.
