Overview
The TPS2051BDGNG4 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. Each switch is controlled by a logic enable input, and the device includes an internal charge pump to manage the power-switch rise and fall times, minimizing current surges during switching.
