BATTERY AND ENERGY MANAGEMENT CIRCUIT WITH TEMPORAL STORAGE MODE

摘要

An energy management circuit (100) for use with one or more rechargeable cells (201) is capable of prohibiting discharge in response to temporal or other inputs. In one embodiment, a control circuit (102) applies a control signal to a discharge control node (105) when a charging current is applied for less than a charging duration threshold. The control signal causes a discharge disconnect switch (202) to open. In another embodiment, the control circuit (102) applies the control signal to the discharge control node (105) 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.
