Abstract
A power management integrated circuit includes a reconfigurable converter connected to a rechargeable battery and a control circuit. The reconfigurable converter includes an inductor to accumulate energy based on an input voltage from a thermoelectric device, provides a wireless sensor node connected to an output node with an output voltage based on the input voltage and an internal input voltage of the rechargeable battery, operates in one of operation modes based on an available power provided from the thermoelectric device and a power consumption by the wireless sensor node and drives the wireless sensor node in response to the wireless sensor node consuming a current greater than a maximum current generated by the thermoelectric device. The control circuit to control the reconfigurable converter based on the input voltage, a first voltage of a first switching node, a second voltage of a second switching node and the output voltage.
