200nsec is AWFULLY fast for an 8052 - this kind of performance will need external hardware.
Steve Thats exactly what you do, add external hardware for timing and voltage detection and the short circuit protection is done and is usually integrated in the gate drive circuit. A Fault signal goes to MPU to indicate short circuit has occured after gate is turned off. Mahmood |
