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
