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)

The ADP1196 is available in an ultrasmall 1.0 mm × 1.5 mm,

6-ball, 0.5 mm pitch WLCSP.
