The CXAS42259C/D is a family of high-side load switches designed to operation from 1.5V to 5V input voltage. The load switch pass element is an internal 25 ohm RON P-channel MOSFET which enable the device to support up to 3A of continuous current. Additionally, the load switch supports 1.5V. Logic level control and shutdown features in a tiny 1mm X 1mm 4 pin WLCSP package. The CXAS42259C/D provide a slew rage controlled soft-start turn on of 100μs. The soft-start feature is provided to prevent an in-rush current event from pulling down the input supply voltage. The CXAS42259C/D feature an active load discharge circuit which switches in a 200Ω load when the switch is disabled to automatically discharge a capacitive load. An active pull-down on the enable input keeps the CXAS42259C/D in a default OFF state until the enable pin is pulled above 1.2V. Internal level shift circuitry allows low voltage logic signal to switch higher supply voltages. The enable voltage can be as high as 5.5V and is not limited by the input voltage. The CXAS42259/D with reverse voltage block function, if the VIN disappears or VIN is less than VOUT; device will turn of without leakage current. The CXAS42259/D operating voltage range makes them ideal for Lithium ion and NMH/NiCad/Alkaline battery powered systems as well as non-battery powered applications. The device provides low quiescent current and low shutdown current to maximize battery life.
