SNVSBY7 March 2021 TPS92390
The MODE resistor missing or invalid is detected if the resistor is not assembled or not valid value as requested during the initialization. TPS92390 defaults to phase-shift PWM mode with I2C address 0x3A if the MODE resistor is missing or invalid. The MODESEL_STATUS fault bit will be set in the BOOST_FAULT_STATUS register. The MODE resistor missing or invalid fault is not monitored after initialization, so that the TPS92390 operates in the mode determined during initialization even though the MODE resistor is missing or invalid after initialization.
