Overview
The TPS2061DGNRG4, produced by Texas Instruments, is a power-distribution switch designed for applications where heavy capacitive loads and short-circuits are likely to occur. This device features a 70mΩ N-channel MOSFET power switch, 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 includes an internal charge pump to manage power-switch rise and fall times, minimizing current surges during switching.
