DC MOTOR FULL BRIDGE DRIVER

F TYPE: UNDER DEVELOPMENT

The TA8440H is a full−bridge driver for selecting the forward and

reverse running of a motor with brushes and is able to control 4

modes of forward, reverse, stop and braking.

The motor driving unit and the control unit have a separate power

supply line, independently and the TA8440H is also usable as a

stepping motor driver.
