Data Sheet

REGISTER 9: TH_CFG (TEMPERATURE WARNING AND LOW VIN WARNING THRESHOLD CONFIGURATION),

ADDRESS 0x09

Register 9 is used to configure the junction temperature overheat detection threshold and the low input voltage detection threshold.

When these thresholds are enabled, the TEMP_INT and LVIN_INT status bits in Register 14 are set if the thresholds are exceeded.
