SMA7036M Features

* of SMA7029M. The basic function pins are compatible with those of SMA7029M. Connect TTL or similar to the SYNC terminals and switch the SYNC terminal level high or low. When the motor is not running, set the TTL signal high (SYNC terminal voltage: 4 V or more) to make chopping synchronous. When the
