Overview
TA8440H/F TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC TA8440H,TA8440F 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.
TA8440H FEATURES l Output current is as large as 1.
5A (AVE) and 3.
0A (PEAK).
l 4 modes of forward, reverse, stop, and braking are available and a counter−electromotive force absorbing diode has been built−in.
l Thermal shutdown circuit incorporated.
l Input is compatible with CMOS.
l Built−in input pull−up resistor.
BRAKE = 200 kΩ (Typ.
) l Built−in input pull−down resistor.
