6.3.7.2.1 Overcurrent and Overtemperature Protection

The device has an overcurrent protection circuit that limits the current drawn out of the MICBIAS output to the maximum supported level when an external undesired short event occurs on the MICBIAS pin. The device sets the status flag, P1_R59_D2 bit, on an overcurrent detection. Additionally, the device has an overtemperature detection circuit that is enabled by default and sets the status flag, P1_R52_D5 bit, whenever the die junction temperature goes higher than the supported level.

Additionally, the P1_R80 and P0_R66_D[4:3] register can be configured to shutdown MICBIAS along with the on-chip boost on an overtemperature detection. TI recommends configuring PD_ON_FLT_CFG, P0_R66_D4-3 to '10' so that on an overtemperature detection, the device powers-down MICBIAS, the on-chip boost, and all ADC channels.

More details and information on fault diagnostics are discussed in the TAC5xxx-Q1 Fault Diagnostics, Interrupts, and Protection Features application report.
