Bi-DIRECTIONAL MOTOR DRIVER WITH BRAKE FUNCTION

M54641L/FP

MITSUBISHI <CONTROL / DRIVER IC>

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.
