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
: V_CC (opr.) = 6 to 18 V (P, AP),
V_S (opr.) = 0 to 16 V (P) / = 0 to 18 V (AP)
No malfunction occurs even if V_CC is higher than V_S or vice versa. However, observe V_ref ≤ V_S.
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
