REGISTER 9: TH_CFG (TEMPERATURE WARNING AND LOW V
IN
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.
