Preliminary Datasheet
5-CHANNEL MOTOR DRIVER FOR DVD PLAYER
General Description
Features
The AM5669 is a five-channel BTL driver IC, in
which four channels are voltage type BTL drivers for
tracking and focus actuators, sled and spindle motors,
the other one channel is DC motor driver for tray
which supports forward/reverse control. This IC also
contains two independent precise voltage regulators
with adjustable range from 1.5V to 4V and a free comparator for spindle channel motor direction detection.

Application Information
6. Tray driver logic input:
1. The built-in thermal shutdown circuit mutes the
output current when the chip temperature reaches
175oC (Typ). The hysteresis is set to 30oC (Typ), so the
circuit will start up again when the chip temperature
falls to 145oC (Typ).
2. In case mute pin voltage is under 0.5V or this pin is
not connected, output current is muted (except for tray
motor driver). Mute pin voltage should be more than
2.0V for normal application.
3. Bias pin (pin 27) should be pulled up to more than
1.2V. In case the bias pin voltage is pulled down below
0.9V (Typ), the output current is muted.

Input circuit of pins 6 and 7 is designed to avoid
simultaneous activation of upper and lower output
tray; however, in order to improve reliability, apply
motor forward/reverse input once through open mode.
We recommend time period for open longer than
10msec.
4. Insert the bypass capacitor (about 0.1µF) between
VCC1,2 pin and GND pin as close as possible to this
chip.
"H" side output voltage on output pins (VOTR+ or
VOTR-) varies depending on output control terminal
for tray (pin 21). "H" side output voltage is set to three
times (9.2dB Typ) the voltage of VCTL (pin 21). And,
"L" side output voltage is equal to output saturation
voltage.
5. Heat dissipation fins are attached to the GND on
the inside of the package. Make sure to connect them
to the external GND.
