The CXAS42261 is a N-channel MOSFET power switch designed for high-side load-switching applications, and the device has a typical RDS(ON) of 12m and the output current is limited to 9A.The CXAS42261 has a programmable turn-on load switch and offers a shutdown load discharge circuit to rapidly turn off a load circuit when the switch is disabled. The CXAS42261 operates with an input voltage ranging from 0.6V to 5.5V. The CXAS42261 also features an under voltage lock out which turns the switch off when an input under-voltage condition exists. In shutdown mode, the supply current decreases to about 2μA. The CXAS42261 is available in 8 pin ADFN package.
