Overview
The TPS2061DBVT, produced by Texas Instruments, is a current-limited, power-distribution switch 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 gate drive is provided by an internal charge pump that minimizes current surges during switching. The charge pump allows operation from supplies as low as 2.7V without requiring external components.
