GENERAL DESCRIPTION

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

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

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.
