SA1582
BIDIRECTIONAL DC MOTOR DRIVER FOR DISK TRAY MOTION
DESCRIPTION
The SA1582 is a monolithic IC of driving bi-directional DC motor with
braking and speed control. It can be drove the loading motor driver of
CDP, VCR, and TOY etc.
By changing the voltage of the two logic input pins, the chip can control
the motor’ forward/reverse and braking. And it is also easy to adjust the
s
speed of motor by changing the voltage of the speed control pin.
SOP-8-225-1.27
DIP-8-300-2.54
FEATURES
* Built-in brake functions for stable brake characteristics.
* Built-in element to absorb a surge current derived from changing
motor direction and braking motor drive.
* Motor speed control by an external voltage.
* Stable motor direction change.
* Interfaces with CMOS devices.
* Built-in the thermal shut down circuit (165°C).
* Low standby current. (6.5mA)
