Overview
The TPS22915BYFPR is a 5.5-V, 2-A, low on-resistance load switch produced by Texas Instruments. This device is part of the TPS22914/15 series and features an integrated single-channel load switch with an N-channel MOSFET. It operates over an input voltage range of 1.05 V to 5.5 V and supports a maximum continuous current of 2 A. The switch is controlled by an on and off input, which can interface directly with low-voltage control signals. The device is ideal for space-constrained, battery-powered applications due to its small size and low on-resistance.
