Abstract
A device includes a current monitor, an electronic switch, an energy harvester, and a load controller. The current monitor monitors current drawn by a load coupled to the device and generate an alert signal in response to the monitored current exceeding a predefined threshold value. The electronic switch decouples a battery from the load in response to the alert signal, the electronic switch being electrically disconnected from a negative terminal of the battery coupled to the device. The energy harvester stores energy from the battery while the load is drawing current from the battery. The load controller receives, from the energy harvester, the stored energy from the energy harvester and generates a voltage to power the current monitor to reset the alert signal while the battery is decoupled from the load.
