Overview

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 driver.

Key Features

  • z Output current is up to 1.5 A (AVE. ) and 3.0 A (PEAK). z 4 modes of forward, reverse, stop, and braking are available and a back-electromotive force absorbing diode has been built-in. z Thermal shutdown circuit incorporated z Input is compatible with CMOS. z Built-in input pull-up resistor. BRAKE = 200 kΩ (typ. ) z Built-in input pull-down resistor. IN, ENABLE = 100 kΩ (typ. ) Weight: 4.04 g (typ. ) The TA8440HQ: The TA8440HQ is Sn-Ag plated product including Pb. The following conditions apply.
