Abstract
Various examples disclosed herein relate to current sensing via current sensing circuitry, and more particularly, to calibrating current sensing circuitry to dynamically detect current ranges across a load. In an example embodiment, a microcontroller unit (MCU) is provided herein that includes a processor and current sensing circuitry coupled to the processor. The current sensing circuitry of the MCU is configured to measure voltages associated with a load. The processor of the MCU is configured to obtain the measured voltages from the current sensing circuitry, identify a temperature drift of the current sensing circuitry that exceeds a threshold value, update parameters with which to determine a current associated with the load based on the temperature drift, and determine the current associated with the load based on the updated parameters and the measured voltages.
