Forward/reverse rotation setting pin.
A low-level specifies forward rotation
and a high-level specifies reverse
rotation. This pin is held low when open.
TGND
Test pin. Connect this pin to ground.
5V regulator output pin
(control circuit power supply).
Insert a capacitor between this pin and
ground for power stabilization.
0.1μF or so is desirable.
Output current detection pin.
This pin is used to detect the voltage
across the current detection resistor
(Rf).
The maximum output current is
determined by the equation I OUT =
0.25V/Rf.
Thermistor connection pin.
The thermistor detects heat generated
from HIC and turns off the drive output
when an overheat condition occurs.
If the pin voltage is 0.6V or lower, the
drive output is turned off.
