Component Description
1. Control Input/PWM Input Circuit
The input signals are shown below. Input at the CMOS and TTL levels can be provided. Note that the
input signals have a hysteresis of 0.2 V (typ.).

PWM control function
Motor speed can be controlled by inputting the 0/5-V PWM signal to the PWM pin.
When PWM control is provided, normal operation and short brake operation are repeated.
If the upper and lower power transistors in the output circuit were ON at the same time, a penetrating
current would be produced. To prevent this current from being produced, a dead time of 300 ns (design
target value) is provided in the IC when either of the transistors changes from ON to OFF, or vice versa.
Therefore, PWM control by synchronous rectification is enabled without an OFF time being inserted by
external input. Note that a dead time is also provided in the IC at the time of transition between CW
and CCW or between CW (CCW) and short brake mode, thereby eliminating the need for an OFF time.
