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.
