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.
