Note 1: Select the optimum value for the capacitor by experiment.

Note 2: Insert the current limiting resistor R1 to protect the IC from overcurrent.

Note 3: When VS = Vref, insert the resistor R2 (3 kW or more) to protect the Vref pin from being damaged by a

surge.

Note 4: The IC may be destroyed due to short circuit between output pins, an output pin and VCC, or an output pin

and ground. Design the output line, VCC (VM, VS, VEE) lines and the ground line with great care.

Note

· Shoot-through current occurs when the mode is switched. The driver must enter the stop mode for

approximately 100 ms before switching between CW and CCW modes, or CW/CCW and brake modes.

· The proper IC functions are not guaranteed at power on/off. Before using the IC, check that any IC malfunctions

that are possible at power on/off will not cause a problem in the IC application.
