7.6.9 FAULT_STATUS Register (0x21)

The FAULT_STATUS register provides information about the source of the FAULT signal. The host must clear

each fault flag by writing a 1 to the bit that is set. The exception is bit 4, which may be written 1 or 0 as needed

to implement self-test of the IC stack and wiring.

I_FAULT

The device has failed an internal register consistency check.

Measurement data and protection function status may not be

accurate and should not be used.

0 = No internal register consistency check fault exists.

1 = The internal consistency check has failed self-test. The host

should attempt to reset the device, see the RESET section. If

the fault persists, the failure should be considered uncorrectable.

FORCE

This bit asserts the FAULT signal. It can be used to verify

correct operation and connectivity of the FAULT line as a part of

system self-test.

0 = Deassert FAULT (default)

1 = Assert the FAULT signal

POR

This bit indicates a power-on reset (POR) has occurred.

0 = No POR has occurred since this bit was last cleared by the

host.

1 = A POR has occurred. This notifies the host that default

values have been loaded to Group1 and Group2 registers, and

OTP contents have been copied to Group3 registers.

CRC

This bit indicates a garbled packet reception by the device.

0 = No errors

1 = A CRC error was detected in the last packet received.

CUV

This bit indicates that this bq76PL536A has detected a cell

undervoltage

(CUV)

condition.

Examine

CUV_FAULT

determine which cell caused the ALERT.

0 = All cells are above the CUV threshold (default).

1 = One or more cells is below the CUV threshold.

COV

This bit indicates that this bq76PL536A has detected a cell

overvoltage

(COV)

condition.

Examine

COV_FAULT

determine which cell caused the FAULT.

0 = All cells are above the COV threshold (default).

1 = One or more cells is below the COV threshold.
