SLUSE14A December 2020 – February 2021 BQ76942
The RST_SHUT pin provides a simple way to reset or shutdown the BQ76942 device without needing to use serial bus communication. During normal operation, the RST_SHUT pin should be driven low. When the pin is driven high, the device will immediately reset most of the digital logic, including that associated with the serial communications bus. However, it does not reset the logic that holds the state of the protection FETs and FUSE, these remain as they were before the pin was driven high. If the pin continues to be driven high for 1 second, the device will then transition into SHUTDOWN mode, which involves disabling external protection FETs, and powering off the internal oscillators, the REG18 LDO, the on-chip preregulator, and the REG1 and REG2 LDOs.
