ADI ADP197ACBZ-R7

The ADP197 is a high-side load switch powered by a 1.8 V to 5.5 V supply. This load switch provides battery domain isolation, helping to extend power domain isolation. It integrates a low on-resistance N-channel MOSFET supporting continuous currents above 3 A with minimal power dissipation. The ADP197 features a low quiescent current of 18 μA and ultralow shutdown current, making it ideal for battery-powered portable devices. With a built-in enable logic level translator, the ADP197 is compatible with a wide range of processors and GPIO controllers. If the junction temperature exceeds 125 °C, the overtemperature protection circuit activates to protect the device itself and downstream circuitry from damage. The ADP197 delivers excellent operating performance while occupying minimal PCB space — less than 1.5 mm² in area and only 0.60 mm in height. The ADP197 is available in a 6-ball, 1 mm × 1.5 mm, 0.5 mm pitch, ultra-compact WLCSP package.
