The CXAS42260 advanced load-management switches target applications requiring a highly integrated solution. If disconnects loads powered from DC power rail (<6V) with stringent off-state current targets and high load capacitances (up to 200μF). Each switch consists of slew-rate controlled low-impedance MOSFET switch (23mΩ type) and other integrated analog features. The slew-rate controlled turn-on characteristic prevents inrush current and the resulting excessive voltage droop on power rails. The CXAS42260 has TRCB function blocking unwanted reverse current from VOUT to VIN during ON/OFF state. These device have exceptionally low off state current drain (<2μA max) which facilitate compliance in very low stand by power applications. The input voltage range operates from 1.5V to 5.5V DC to support a wide range of applications in consumer. Optical, medical storage, portable and industrial device power management. Switch control is managed by a logic input (Active HIGH) capable of interfacing directly with low voltage control signal/GPIO with no extremely pull-down resistor required. The device is packaged in WLCSP2X3 -6 pin.
