TA8083P/F
TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA8083P,TA8083F
DUAL DC MOTOR DRIVER
The TA8083P、TA8083F contains two motor driver circuits with
a current capacity of 0.5A for directly driving bidirectional DC
motors. Inputs DI1 A / B and DI2 A / B are combined to select one
of forward, reverse Stop, and brake modes. Since the inputs are
TTL-Compatible, this IC can be controlled directly from a CPU or
other control system.
In addition, the IC also has a low standby current function, a
self-diagnostic function, and various protective functions.
FEATURES

TA8083P/F
DESCRIPTION OF MULTI-PROTECTIVE OPERATION
The TA8083P、TA8083F has functions for protection from over-voltage (VSD), over-current (ISD), and overheat
(TSD). These functions protect the IC (and the motor load in some cases) from deterioration or destruction due
to power-related overstress.
The three functions work independently.
Each function is explained below.
1. Over-voltage protection (VSD)
· Basic operation
When the voltage supplied to the VCC pin is up to the VSD detection voltage, the output is controlled by the
input signals. However, when the VCC voltage exceeds the detection voltage, the output enters
high-impedance state regardless of the input signals.
· Detailed explanation
The VSD voltage is detected by comparing the Zener voltage with the voltage obtained by dividing VCC with
a resistor. When the center voltage of the resistor is higher than the Zener voltage, a transistor-off
instruction is issued to the control logic. When it is lower than the Zener voltage, the logic is controlled by
the input signals from DIA and DIB.
2. Overheat protection (TSD)
· Basic operation
When the junction (chip) temperature is up to the TSD detection temperature, the output is controlled by
the input signals. When it exceeds the TSD detection temperature, the output enters high-impedance state
regardless of the input signals.
· Detailed explanation
The temperature is detected by monitoring VF of a diode on the chip. When the diode VF is lower than the
internal reference voltage, an output transistor-off instruction is issued to the control logic. When it is
higher than the internal reference voltage, the logic is controlled by the input signals from DIA and DIB.
