TA8440H/HQ TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8440H/HQ Full-bridge Driver (H-Switch) for DC Motor (Driver for Switching between Forward and Reverse Rotation) The TA8440H/HQ is a full-bridge driver for selecting the forward and reverse running of a motor with brushes and can control four modes: forward, reverse, stop and braking. The motor driving unit and the control unit have a separate power supply line, and the TA8440H/HQ can also be used as a stepping motor drive.
