TPS389C03-Q1 device option comes preprogrammed with default values for over voltage, under voltage.
NIRQ pin requires a pull up resistor in the range of 1 kΩ to 100 kΩ.
NRST pin requires a pull up resistor in the range of 1 kΩ to 100 kΩ.
WDO pin requires a pull up resistor in the range of 1 kΩ to 100 kΩ.
SDA and SCL lines require pull up resistors in the range of 10 kΩ.
The safety microcontroller is used to clear fault interrupts reported through the NIRQ interrupt pin and the INT_SCR1 and INT_SCR2 registers. The interrupt flags can only be cleared by the host micrcontroller with a write-1-to-clear operation; interrupt flags are not automatically cleared if the fault condition is no longer present.
