SLUUCJ0 November 2023 BQ76907
The REGOUT LDO integrated in the BQ76907 device includes circuitry to detect an error condition, such as the regulator is in short circuit current limit, or if the die temperature exceeds approximately 120°C. When an error condition is detected, the device disables the REGOUT LDO, triggers the REGOUT Diagnostic Protection Fault, and sets 0x05 Safety Status A()[REGOUT], if enabled. The device can disable FETs based on the setting of Settings:Protection:Both FET Protections B[REGOUT]. When an overtemperature condition is detected, the device can transition to SHUTDOWN mode if Settings:Configuration:Power Config[OTSD] is set. The fault is recovered if the cause of the error is removed (such as the short circuit is removed or the regulator temperature falls below the overtemperature threshold). This check operates in DEEPSLEEP mode as well as NORMAL and SLEEP modes.
