SNVSBY7 March 2021 TPS92390
The TPS92390 has an INT pin to alert the host when a fault occurs. If I2C interface is available, the Interrupt Fault Status registers can be read back to learn which fault(s) have been detected. These status bits are located in the SUPPLY_STATUS, BOOST_STATUS and LED_STATUS registers. Each interrupt status has a STATUS bit and a CLEAR bit. To clear a fault interrupt status a 1 must be written to both the STATUS bit and CLEAR bit at the same time.
