Cautions and Warnings

Terminal connection

To avoid malfunction, terminals of this IC should not be left open.

Operation of the protection circuit

(OCP,TSD)

This product has two protection circuits (OCP and TSD). These protection circuits

work by detecting excessive applied to the driver. Therefore, these function are

not able to protect if the power exceeds the tolerance of the driver.

Handling

When static electricity is a problem, care should be taken to properly control

the room humidity, especially in the winter when static electricity is most

troublesome.

IC

Care should be taken with device leads and with assembly sequence to avoid

applying static charges to IC leads. PC board pins should be shorted together to

keep them at the same potential to avoid this kind of trouble.

Cautions for Storage

Ensure that storage conditions comply with the standard temperature (5°C to

35°C) and the standard relative humidity (approximately 40% to 75%) and avoid

storage locations that experience extreme changes in temperature or humidity.
