发明名称 Battery protection circuit for simulating an overcurrent condition based on battery current flow
摘要 A battery protection circuit is provided that includes current monitoring circuit. The current monitoring circuit senses current flowing to or from a rechargeable cell. When the current exceeds a maximum value, the current monitoring circuit actuates, whereby opening a transistor. The transistor has a resistor couple in parallel. When the transistor opens, current is forced through the resistor coupled in parallel with the transistor, thereby limiting the current to a maximum value. The current monitoring circuit also simulates an overcurrent condition in the safety circuit. The overcurrent condition causes a disconnect switch to open, thereby disconnecting the cell(s) from the external terminals.
