Functional Description
Overcharge
If the battery voltage rises over the overvoltage high limit, charging is stopped by opening the power switch.
The switch is closed again when:
•
•
Overdischarge
If the battery voltage falls under the undervoltage low limit, discharging is stopped by opening the power switch.
The switch is closed again when:
•
•
The battery voltage falls below overvoltage low level (self discharge of the battery).
A discharge current is detected.
The battery voltage rises over undervoltage high level.
A charge current is detected.
