ETC AT5608

AT5608
Bi-directional Motor Driver
Features
Description
˙Built-in brake function.
˙Built-in diode to absorb surge currents.
˙Low standby circuit current .
˙ Wide range of operating supply voltage
(4.5~13.5V).
˙Interfaces with the TTL logic.
The AT5608 is a monolithic integrated circuit
designed for driving bi-directional DC motor.
It has two pins of logic input for controlling the
forward/reverse and braking, which can supply an
output current of up to 100mA (typical)
according to the logic control.
Applications
DVD and VCD player tray driver.
