The ADP197 is a high-side load switch designed for operation between 1.8 V and 5.5 V. This load switch provides power domain isolation， which helps extend battery operation. The device contains a low on-resistance， N-channel MOSFET that supports more than 3 A of continuous current and minimizes power loss. The low 18 μA quiescent current and ultralow shutdown current make the ADP197 ideal for battery-operated portable equipment. The built-in level shifter for enable logic makes the ADP197 compatible with many processors and GPIO controllers.

　　Overtemperature protection circuitry activates if the junction temperature exceeds 125°C， thereby protecting itself and downstream circuits from potential damage.

　　The ADP197-02 incorporates an internal quick output discharge （QOD） circuit to discharge the output capacitance when the ADP197-02 output is disabled

　　In addition to operating performance， the ADP197 WLCSP package occupies minimal printed circuit board （PCB） space with an area of less than 1.5 mm2 and a height of 0.60 mm.

　　The ADP197 is available in an ultrasmall 1.0 mm × 1.5 mm， 0.5 mm pitch， 6-ball WLCSP and a 2.0 mm × 2.0 mm × 0.55 mm， 0.65 mm pitch， 6-lead LFCSP.
