CXAS42287 is a low on-resistance dual channel load switch with programmable turn-on rise time. It contains two n-channel MOSFETS that can provide 6A maximum continuous current per channel. Each channel can operate over an input voltage range of 0.8V to 5.5V. Each channel can be independently controlled by a low-voltage control signal through EN1/EN2 pin. In CXAS42287, a 200Ω load resistor is integrated for quick output discharge when load switch is turned off
