Startup and
Shutdown Limits
The user-programmable startup and shutdown limits allow for adjustable
startup and shutdown voltages. These limits can be adjusted for different
numbers of battery cells, or for the particular requirements of the base
station operation. Once the limits are reached, the PMU will shut down.
Battery Protection
Limits
The battery protection limits are set in hardware at the factory, and cannot
be adjusted by the user. These limits will not be reached under normal
operation conditions, but are provided as “fail-safe” measures to protect the
battery from deep discharge. They also remove the need for low-voltage
disconnect modules.
