Dual-Bridge Drivers (for Switching between Forward and Reverse Rotation) for DC Motors

The TA7279P and TA7279AP can control a DC motor in four

modes (forward rotation, reverse rotation, stop, and brake), using

their bridge driver best suited for switching between forward and

reverse rotation.

These ICs can deliver an output current of 1.0 A (AVE.) and 3.0 A

(PEAK). They can adjust the motor voltage easily because they

have a circuit configuration best suited for VCR front loading,

tape loading, and reel rotation as well as power supply pins

separately for two sections (output and control). In addition, they

can be connected directly to CMOS devices because their input

current is low.

Features

Weight: 3.00 g (typ.)

z Wide range of operating voltage

: VCC (opr.) = 6 to 18 V (P, AP),

VS (opr.) = 0 to 16 V (P) / = 0 to 18 V (AP)

No malfunction occurs even if VCC is higher than VS or vice versa. However, observe Vref ≤ VS.

z Output current up to 1.0 A (AVE.), 3.0 A (PEAK)

z Built−in thermal shut down circuit

z Built-in back electromotive force absorber diode

z Built-in hysteresis circuit
