The CXAS42281 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 each channel. In shutdown mode, the supply current decreases to less than 1μA. The CXAS42281 is available in a 8 pin TDFN 2X2mm package.The CXAS42281 is a dual P-channel MOSFET power switch designed for high-side load-switching applications. Each MOSFET has a typical RDS(ON) of 74mΩ at VCC=5V, allowing increased load switch current handling capacity with a low forward voltage drop. The CXAS42281 has a slew rate limited turn-on load switch and offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. An additional feature is a slew-rate selector pin which can switch between fast and slow slew rate.
