Overview
The TPS2042BDGN is a dual-channel, current-limited power-distribution switch produced by Texas Instruments. This device is designed for power-distribution systems that require multiple power switches in a single package, making it ideal for applications where heavy capacitive loads and short circuits are likely to be encountered. The TPS2042BDGN incorporates 70mΩ N-channel MOSFET power switches and features an internal charge pump to control the power-switch rise and fall times, minimizing current surges during switching.
