2.2.2.2.4 Functional Safety

The TPS650330-Q1 device has integrated supervisors in addition to temperature and current monitoring. The interrupt pin or status bits of this PMIC can be used to detect when a fault condition has occurred, at which point a local or remote MCU or processor can query the fault mechanism via I2C, and take the appropriate action. The TPS650330-Q1 is also pin-compatible with the TPS650331-Q1, TPS650332-Q1, and TPS650333-Q1. Each of these devices provides additional safety features, allowing the scalability of this design to camera applications requiring functional safety.
