Overview
The TPS2051BDBVT is a power-distribution switch from Texas Instruments, designed for applications where heavy capacitive loads and short circuits are likely to be encountered. This device incorporates a 70mΩ N-channel MOSFET power switch, making it suitable for power-distribution systems that require multiple power switches in a single package. The TPS2051BDBVT is controlled by a logic enable input and features an internal charge pump to manage power-switch rise and fall times, minimizing current surges during switching.
