Abstract
An energy management circuit () for use with one or more rechargeable cells () is capable of prohibiting discharge in response to temporal or other inputs. In one embodiment, a control circuit () applies a control signal to a discharge control node () when a charging current is applied for less than a charging duration threshold. The control signal causes a discharge disconnect switch () to open. In another embodiment, the control circuit () applies the control signal to the discharge control node () after failing to detect a charging current for at least a non-charging duration threshold. Discharge can again be allowed by applying a charging current for at least a reset duration.
