Overview
The TPS2052BDRBR, produced by Texas Instruments, is a current-limited, power-distribution switch designed for applications requiring multiple power switches in a single package. This device incorporates 70mΩ N-channel MOSFET power switches, making it suitable for power-distribution systems that encounter heavy capacitive loads and short circuits. The internal charge pump controls the power-switch rise and fall times to minimize current surges during switching, and it operates from supplies as low as 2.7 V without requiring external components.
