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.
