CAUTIONS

Since the thermal protection function of this IC may not work in abnormal status (oscillation, low supply voltage,

output short-circuit, etc.), check the operation in the IC installation status when using this function.

When the motor back electromotive force is large with the brakes applied, for example, malfunction may occur in

internal parasitic Di.

If flyback current of 1A or more flows, add Schottky Di to the portion between the output and the GND.

When the IC is used at a high speed for PWM, etc., note that switching of output results in delay of approx. 10

µs.
