Reducing current leakage and improving shelf life time of battery-based-devices

An electronic device, comprising:

• a rechargeable battery that has a first terminal coupled to a battery voltage signal and a second terminal coupled to a reference voltage signal;
• an electrical circuit coupled to the battery voltage signal and the reference voltage signal and configured to generate a power mode control signal;
• a battery safety circuit that has a first port coupled to the battery voltage signal and a second port coupled to the reference voltage signal;
• and
• a power down mode circuit that receives the power mode control signal;
• wherein if the power mode control signal has a first value, the power down mode circuit is configured to force a voltage at the first port 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.

• a battery safety circuit that has a first port coupled to the battery voltage signal and a second port coupled to the reference voltage signal;
• and
• a receiver that wirelessly receives a shut down command;
• wherein, in response to the received shut down command, a voltage at the first port is forced to a voltage value relative to 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.
