Product Details

The ADP196 is a high-side load switch designed for operation from 1.8 V to 5.5 V. This load switch provides power domain isolation, helping to 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. In addition, RDSON is constant, independent of the VIN voltage. The low 25 μA quiescent current and ultralow shutdown current make the ADP196 ideal for battery-powered portable equipment. The built-in level shifter for enable logic makes the ADP196 compatible with many processors and GPIO controllers.

Overtemperature protection circuitry is activated if the junction temperature exceeds 125°C, thereby protecting the ADP196 and downstream circuits from potential damage. Overcurrent pro- tection is provided in the form of constant current limiting.

The ADP196-01 incorporates an internal quick output discharge circuit to discharge the output capacitance when the ADP196-01 output is disabled.

The ADP196 in the WLCSP package occupies minimal printed circuit board (PCB) area with a footprint of less than 1.5 mm2 and a height of 0.60 mm.

The ADP196 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.
