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. 10µs.
