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

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.

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

Built−in thermal shut down circuit

Built-in back electromotive force absorber diode

Built-in hysteresis circuit
