ABSTRACT:
An interface circuit between a microcomputer and a MOSFET driver for motor control includes logic for failsafe motor control particularly to protect the driver. AND gates supply driver signals when a set of conditions are met. Certain conditions are mandated directly by the microcomputer. An analog oscillator and digital counter are used to time data signals from the microcomputer to assure continual computer operation. Other conditions are determined by the logic and include monitoring faulty motor current conditions, assuring that forward and reverse signals are not given concurrently, and assuring that there is a dead time between forward and reverse signals to the driver.
