Cell-Balancing/Discharge Switch Enable:
Select cell-balancing/discharge switches to activate. Set BAL[N] to 1 to enable the cell-
balancing switch between C
switch. The switches are separately disabled by signals from the die overtemperature
detection circuit and the cell-balancing watchdog timer.
Write ignored; read back 0.
Cell-Balancing Timer Predivider:
Sets the step size of the cell-balancing timer LSB.
00 = Disabled, no timeout for the cell-balancing switch on-time.
01 = 1s; timer range is then 1s to15s.
10 = 4s; timer range is then 4s to 60s.
11 = 16s; timer range is then 16s to 240s.
Cell-Balancing Timer:
Acts as a safety watchdog timeout for the cell-balancing switches. The timer counts down
at a rate set by the CBPDIV bits. When the timer reaches 0, all cell-balancing switches are
disabled. The timer should be periodically rewritten with a timeout value to keep the cell-
balancing switches enabled. When the timer value is read, the value reported is latched
during the 9th bit time following the ACQCFG register address of the READALL command.
Write ignored; read back 0.
