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. VBUS has overvoltage protection with its level being set by an optional external resistor divider. If no overvoltage protection is desired, it may be disabled by grounding the OVP terminal. The TPS6602x series supports a fault pin that indicates overcurrent and overtemperature events.
TPS6602x series also supports a high voltage VBUS LDO regulator (3.3-V or 5-V per device type) useful for supplying power to the device and other system components when operating in dead battery conditions. The TPS66020 regulates to 3.3-V and the TPS66021 regulates to 5-V.
