voltage and undervoltage comparators. The threshold
references for the comparators are set by the UVSEL_
and OVSEL_ input pins. When one of the cell voltages
exceeds V OV or is below V UV when V UV is enabled, the
internal cell out-of-range signal for the given cell is set
and logically ORed with the same signal for the other
cell positions to create an overall out-of-range signal.
When any cells are out-of-range as indicated by the
internal out-of-range signal, an internal current source
begins to charge the capacitor C DLY connected to the
CD pin. If the voltage at the CD pin reaches V CD , the
ALRM L line is set to V AA (+2.4V minimum as referred to
AGND). Normally, the ALRM L line is a heartbeat signal
with pulses occurring every 250μs. If all cell voltages
transition from out-of-range to in-range before the volt-
age at pin CD reaches V CD , an internal switch clamps
the CD pin to GND. This action discharges C DLY and,
because the delay had not yet expired, no alarm
occurs. Discharging C DLY ensures that the full delay
time occurs for the next overvoltage or undervoltage
