TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8400P/PG
Sequential Dual-Bridge Driver (Driver for Switching between Forward and Reverse
Rotation) for DC Motors
A bridge driver ideal for switching between forward and reverse
rotation, the TA8400P/PG can control a DC motor in four
different modes: forward rotation, reverse rotation, stop, and
brake.
The IC can deliver an output current of 0.4 A (ave.) and 1.0 A
(peak). It can adjust the motor voltage easily because it has a
circuit configuration especially well suited for VCR front loading
and tape loading, separate power supply pins for the two sections
(output and control), and a Vref pin at the output for controlling
the motor voltage. In addition, it can be connected directly to
CMOS devices due to its low input current.
Features
Wide range of operating voltage: VCC (opr.) = 4.5 to 18 V
VS (opr.) = 0 to 22 V
Vref (opr.) = 0 to 22 V
No malfunction occurs even if VCC is higher than VS or vice versa. However, ensure Vref ≤ VS.
Output current up to 0.4 A (ave.) and 1.0 A (peak)
Built-in thermal shutdown circuit
Punch-through current restriction circuit
Built-in back electromotive force absorber diode
Hysteresis for all inputs
Weight: 1.11 g (typ.)
