The input voltage ranges of the IN1, IN2, OSC/PWM and SB inputs must be as follows. These inputs are
CMOS- and TTL-compatible, and have a hysteresis of 0.2 V (typ.).
The PWM input frequency should be 100 kHz or less.
In Standby mode, all circuits are turned off, except the standby and 5-V circuits.
To bring the device out of Standby mode, IN1 and IN2 must be set Low once (Stop mode); for a operating
mode must be selected after the power supply becomes stable.
Constant current PWM
For constant-current PWM, V
be connected between OSC/PWM and ground.
Direct PWM
For direct PWM, V
When a PWM signal with an amplitude between 0 V and 5 V is applied to the OSC/PWM input, the OUT1
and OUT2 levels change accordingly, resulting in an alternating sequence of CW/CCW and short brake.
