Overview
The TPS2062CDR is a dual-channel, current-limited power-distribution switch produced by Texas Instruments. This component is part of the TPS20xxC and TPS20xxC-2 family, designed to handle applications where heavy capacitive loads and short-circuits may occur, such as in USB ports, laptops, and desktops. The device operates in a constant-current mode when the output load exceeds the current-limit threshold, providing a predictable fault current under all conditions.
