Pin function
Power-supply voltage pin.
VCC voltage is impressed. The permissible operation voltage is from
4.0 to 16.0(V). The capacitor is connected for stabilization for GND pin
(6pin).
Motor drive control input pin.
Driving control input pin of OUT1 (10pin) and OUT2 (9pin). It is used in
combination with IN2 pin (3pin). For the digital input, range of the "L"
level is 0 to 0.7(V), range of the "H" level is from 1.8 to 5.5(V). PWM can
be input. Pull-down resistance 100(kΩ) is built into in the pin. It becomes
a standby mode because all IN1, IN2, IN3, and IN4 pins are made "L",
and the circuit current can be adjusted to 0.
Motor drive control input pin.
Driving control input pin of OUT1 (10pin) and OUT2 (9pin). It is used in
combination with IN1 pin (2pin). PWM can be input. With built-in
pull-down resistance.

2. About the switch time from the stand-by state to the state of operation
When IN1, IN2, IN3, IN4 are "L", this IC has completely stopped operating. After the time of reset of about 7s of an
internal setting, it shifts to a prescribed output status corresponding to the state of the input when the signal enters the
input terminal.
Reset of about 7s doesn't hang even if the motor is driven from the stand-by state when either CH drives and the output
becomes an output status corresponding to the state of the input. As for full power TR between the reset time, turning
off is maintained.

4. Thermal shutdown function
The thermal shutdown circuit is incorporated and the output is turned off when junction temperature Tj exceeds 180°C.
As the temperature falls by hysteresis, the output turned on again (automatic restoration).
The thermal shutdown circuit does not guarantee the protection of the final product because it operates when the
temperature exceed the junction temperature of Tjmax=150°C.
TSD = 180°C (typ)
ΔTSD = 40°C (typ)
