Abstract
In a microcontroller-based system that controls the operation of equipment such as lights and wipers in an automobile, overcurrent is detected by comparing the total current through the device with a stored level. If the detected current is excessive the devices are independently activated and the current through each device is compared with stored current level for the device. A device having an overcurrent condition is inactivated and the remaining devices are activated.
