Description

The TPS6612x contains an integrated 4-V to 22-V Sink power path. The 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 TPS6612x supports a fault pin that indicates overtemperature events.

The TPS6612x 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 TPS66120 regulates to 3.3 V and the TPS66121 regulates to 5 V.
