TPS66021 Overview
The TPS6602x is a full-featured power switch multiplexer that contains an integrated 5-V Source power path and a 4-V to 22-V Sink power path. The 5-V Source path limits the output current to a safe level by operating in a constant-current mode when the output load exceeds the selected current-limit threshold. Each power path supports overtemperature and reverse current protection.
