BATTERY PACK WITH A BATTERY PROTECTION CIRCUIT

A battery circuit includes a monitoring circuit, an integrator circuit, and a comparator. The monitoring circuit can be used to monitor a cell and generate a monitoring signal indicating a cell voltage of the cell. The integrator circuit accumulates a difference between the monitoring signal and a first predetermined threshold over a time period to generate an integrating output. The comparator compares the integrating output to a second predetermined threshold and generates a control signal.
