TA8405S

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

Weight: 0.92 g (typ.)

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
