The CXAS42270 operates with an input voltage from 1.5V up to 5.5V. It is suitable for 1.8V, 3V and 5V systems. Input logic levels are TTL and 2.5V to 5V CMOS compatible. The typical quiescent supply current is 4μA. In shutdown mode, the supply current decreases to less than 1μA. The CXAS42270 is available in a 6 pin TDFN 1.6X1.6mm package.The CXAS42270 is a single P-channel MOSFET power switch designed for high-side load-switching applications. The MOSFET has a typical RDS(ON) of 80mΩ at VCC=5V, allowing increased load switch current handling capacity with a low forward voltage drop. The CXAS42270 has a slew rate limited turn-on load switch and offers a shutdown load discharge pin connected to OUT to rapidly turn off a load circuit when the switch is disabled.
