GENERAL DESCRIPTION The ADP1190 is an integrated high-side load switch with four Aside from its excellent operating performance, the ADP1190 signal switches, designed for operation from 1.4 V to 3.6 V. occupies minimal printed circuit board (PCB) space with an 2 This load switch provides power domain isolation for extended area less than 1.92 mm and a height of 0.50 mm. The ADP1190 power battery life. The load switch is a low on-resistance is available in an ultrasmall 1.2 mm 1.6 mm, 12-ball, 0.4 mm P-channel MOSFET that supports up to 500 mA of continuous pitch WLCSP. load current and minimizes power loss. Integrated with the load switch are four normally open 2 SPST signal switches. Rev. 0 Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.
