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.
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 k (Typ.)
l Built-in input pull-down resistor. IN, ENABLE = 100 k (Typ.)

APPLICATION CIRCUIT
Note 1: Schottky diode (2GWJ42) to be connected additionally between each output (pin 16 / 19 / 20 / 23) and GND
for preventing Punch-Through Current.
Note 2: Utmost care is necessary in the design of the output line, V
S
and GND line since IC may be destroyed due to
short-circuit between outputs, air contamination fault, or fault by improper grounding.
