Overview
The TPS2041BDBVRG4 is a current-limited, power-distribution switch produced by Texas Instruments. This device is designed for applications where heavy capacitive loads and short circuits are likely to be encountered. It incorporates 70mΩ N-channel MOSFET power switches, making it suitable for power-distribution systems that require multiple power switches in a single package. The device features an internal charge pump that controls the power-switch rise and fall times to minimize current surges during switching, and it operates from supplies as low as 2.7V.
