Cautions and warnings

The calculation of control current

Io＝VREF／Rs

REF Voltage range is 0.1V～1.0V

※

When the REF<0.1V, the accuracy of control current is reduce.

Moreover, if REF voltage is set up more than 2.0V, all outputs will be in OFF state.

Installation to a heat sink

1)Recommended Clamping Torque (to External Heat sink) 0.490～0.822N･m

2)Recommended Silicone

Notice

This driver has C-MOS inputs. Please notice as following contents.

・

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

the room humidity. This is particularly true in the winter when static

electricity is most troublesome.

・

Care should be taken with device leads and with assembly sequencing 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.
