However, for inductive loads, the peripheral driver is designed for those applications where output should be clamped to 35 V or less to avoid latch-up low operating power, high breakdown voltage, high output during turn-off (inductive flyback protection).

Unlike clamp diode capable of handling 800 mA is provided at each most peripheral drivers, a unique fault protection is output for this purpose. In addition, the driver incorporates incorporated on each output. When the load current exceeds circuitry that guarantees glitch-free power up or down 1.0 A (approximately) on any output for more than a built-in operation and a fail-safe feature which puts the output in high delay time, nominally 25 µs, that output will be shut OFF by impedance state when the input is open. its protection circuitry with no affect on other outputs.
