BCD AM5665 5-channel motor driver for dvd player Datasheet

Preliminary Datasheet
5-CHANNEL MOTOR DRIVER FOR DVD PLAYER
General Description
Features
The AM5665 is a 5-channel BTL driver IC, in which
two channels drive DC motor, two channels with current feedback drive the coils, such as the focus and the
tracking actuator of DVD player, and the other one
channel drives the bi-direction DC motor for tray.

Tray Motor Speed Control
The amplitude of output voltage depends on VCTL (pin 21). Connect a resistor between VCTL (pin 21) and
VCC1, and you can obtain different output voltages for tray driver by changing the value of RVCTL. (See Figure 4.)
