Overview
The TPS2061DGNR is a 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 features a 70mΩ N-channel MOSFET power switch, making it suitable for power-distribution systems that require multiple power switches in a single package. The TPS2061DGNR operates within a voltage range of 2.7V to 5.5V and is controlled by a logic enable input. It includes an internal charge pump to manage the power-switch rise and fall times, minimizing current surges during switching.
