Sequential Dual-Bridge Driver (Driver for Switching between Forward and Reverse Rotation) for DC Motor
The TA8405S can control a DC motor in four different modes (forward rotation, reverse rotation, stop, and brake), using its bridge driver best suited for switching between forward and reverse rotation.
The IC can deliver an output current of 0.4 A (AVE.) and 1.0 A (PEAK). It has a circuit configuration best suited especially for VCR front loading and tape loading.
FEATUREs
● Wide range of operating voltage: VCC (opr.) = 4.5 to 22 V VS (opr.) = 0 to 22 V
No malfunction occurs even if VCC is higher than VS or vice versa. However, observe Vref ≤ VS.
● Output current up to 0.4 A (AVE.) and 1.0 A (PEAK)
● Built−in thermal shutdown circuit
● Panch-through current restriction circuit
● Built-in back electromotive force absorber diode
● Built-in hysteresis circuit
