ZHCSR35A November 2019 – August 2020 BQ79600-Q1
PRODUCTION DATA
Device integrates an NMOS open-drain output (NFAULT) to signal the MCU that a fault has occurred in the system (either fault from BQ79600-Q1 or from monitoring IC). The NFAULT driver is enabled when [NFAULT_EN] = 1. When BQ79600-Q1 detects an unmasked fault, NFAULT asserts low. When NFAULT is disabled, the device will set the corresponding flag in FAULT_SUMMARY register but will not assert NFAULT.
If the fault information of stack devices are not transmitted to bridge device through Section 7.3.3.2.2, NFAULT output only indicates faults in BQ79600-Q1.
