Pin Functions

U-phase output pin.

V-phase output pin.

W-phase output pin.

(Built-in spark killer diode)

Output current detection pin.

Connecting Rf between this pin and GND

activates current limiting circuit. Then the

lower over-saturation prevention circuit is

activated in accordance with this pin

voltage. Since the over-saturation

prevention level is set with this voltage,

the lower over-saturation prevention effect

may deteriorate in the high current range

if the Rf value is reduced to an extremely

low level.

Power supply pin for supplying power to

output section in IC.

No.A0299-6/8
