Datasheet
Description of Blocks
1. Power-Saving Function
A power-saving function is included, which allows the system to save power when not driving the motor. The voltage
level on this pin should be set high so as to keep the operation mode. (See the Electrical Characteristics; p.4/14)
2. Motor Control Input
(a) INA and INB Pins
Logic level controls the output logic of H-Bridge.
(See the Electrical Characteristics; p.4/14, and I/O Truth Table; p.7/14)
(b) PWM Pin
Logic level sets the IN/IN or EN/IN drive mode.
(See the Electrical Characteristics; p.4/14 and I/O Truth Table; p.7/14)
(c) TR1 and TR2 Pins
Logic level sets the switching speed of H-Bridge transistors, turn on time and turn off time.
(See the Electrical Characteristics; p.4/14 and I/O Truth Table; p.7/14)

Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
