The FAULT_STATUS[CRC] bit is still set when CRC error is detected, but the FAULT pin remains de-asserted. Fault Recovery Procedure When any error flag in DEVICE_STATUS[], FAULT_STATUS[], or ALERT_STATUS[] is set and latched, the state can only be cleared by host communication via SPI. Writing to the respective FAULT_STATUS or ALERT_STATUS register bit with a 1 clears the latch for that bit. The exceptions are the two FORCE bits, which are cleared by writing a 0 to the bit. The FAULT_STATUS[] and ALERT_STATUS[] register bits are read-only, with the exception of the FORCE bit, which may be directly written to either a 1 or 0. Secondary Protector Built-In Self-Test Features The secondary protector functions have built-in test for verifying the connections through the signal chain of ICs in the stack back to the host CPU. This verifies the wiring, connections, and signal path through the ICs by forcing a current through the signal path. To implement this feature, host firmware should set the FAULT[FORCE] or ALERT[FORCE] bit in the top-most device in the stack. The device asserts the associated pin on the South interface, and it propagates down the stack, back to the base device. The base device in turn asserts the FAULT_H (ALERT_H) pin to the host, allowing the host to check for the received signal and thereby verify correct operation. CELL BALANCING The bq76PL536A has six dedicated outputs (CB1…CB6) that can be used to control external N-FETs as part of a cell balancing system. The implementation of appropriate algorithms is controlled by the system host. The CB_CTRL[CBAL1–6] bits control the state of each of the outputs. The outputs are copied from the bit state of the CB_CTRL register, i.e., a 1 in this register activates the external balance FET by placing a high on the associated pin. The CBx pins switch between approximately the positive and negative voltages of the cell across which the external FET is connected. This allows the use of a small, low-cost N-FET in series with a power resistor to provide cell balancing.
