Abstract:
An electronic device includes a rechargeable battery, an electrical circuit, a battery safety circuit, and a power down mode circuit. The electrical circuit is configured to generate a power mode control signal. The power down mode circuit receives the power mode control signal. If the power mode control signal has a first value, the power down mode circuit is configured to force a voltage at a first port of the battery safety circuit to a voltage value that is less than an under voltage lock out (UVLO) threshold value of the battery safety circuit to transition the electronic device from a normal operating mode to a low current power down mode. The electronic device may further include a wake up mode circuit.
