Abstract
Systems, devices, methods, and techniques are disclosed for performing calibrated measurements of current through switches in an electronic control unit. In one example, a device includes a current sensor system; a controller, operably connected to the current sensor system; and one or more switches, operably connected to the controller. The current sensor system is configured to receive a measurement of current conducted through at least one switch of the one or more switches. The current sensor system is further configured to perform a measurement of calibrated total current for the one or more switches. The current sensor system is further configured to determine a calibrated value of current for the at least one switch, based at least in part on a comparison of the measurement of current conducted through the at least one switch and the measurement of calibrated total current for the one or more switches.
