Overview
The TPS2065DBVR is a power-distribution switch produced by Texas Instruments, designed for applications where heavy capacitive loads and short-circuits are likely to be encountered. This device 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 features an internal charge pump to manage power-switch rise and fall times, minimizing current surges during switching. The TPS2065DBVR operates from supplies as low as 2.7V and is packaged in a SOT-23-5 format.
