CALIBRATION OF CIRCUITRY PARAMETERS FOR CURRENT SENSING
DRIVE
September 26, 2024
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.
