Description of Blocks

(ⅱ)External Pin Control

■

Voltage Driver (only at speed control = OFF)

The PWM drive is executed by the PWM duty ratio which is controlled by the register setting. The PWM direction and

PWM ON/OFF are controlled by INA/INB pin.

■

Current Driver

The constant current drive is executed by the output current value which is controlled by the register setting. Constant

current driving direction and turning ON/OFF are controlled by INA/INB pin.
