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
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.
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.
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.
