GENERAL DESCRIPTION
The ADP1196 is a high-side or low-side load switch designed for
VIN operation between 0 V and 5.5 V with a VB_EN supply of
1.83 V to 5.5 V. The device contains an internal charge pump that
operates from either VIN or VB_EN, whichever is higher, and
an ultralow on resistance, N-channel MOSFET. This N-channel
MOSFET supports more than 2 A of continuous current at VIN
close to 0 V, and, with its ultralow on resistance, minimizes power
loss. In addition, the on resistance is constant, independent of the
VIN or VB_EN voltage. The low 26 µA quiescent current and
ultralow shutdown current make the ADP1196 ideal for low
power applications.

When the junction temperature exceeds 125°C, overtemperature
protection circuitry is activated, thereby protecting the ADP1196
and downstream circuits from potential damage.
The ADP1196 occupies minimal printed circuit board (PCB)
space, with an area of less than 1.5 mm2 and a height of 0.60 mm.
The ADP1196 is available in an ultrasmall 1.0 mm × 1.5 mm,
6-ball, 0.5 mm pitch WLCSP.
