Overview
The TPS22975DSGR is a single-channel load switch produced by Texas Instruments. It is part of the TPS22975 product family, which includes the TPS22975 and TPS22975N devices. This load switch is designed to provide a configurable rise time to minimize inrush current and features an N-channel MOSFET that can operate over an input voltage range of 0.6 V to 5.7 V. The device supports a maximum continuous current of 6 A and is controlled by an on and off input (ON) that can interface directly with low-voltage control signals.
