5-channel BTL Driver for DVD player
AM5766
The AM5766 is a five-channel BTL driver IC for driving the motors and actuators such as used in DVD player and
consists of two independent precision voltage regulators with adjustable range from 1.25V to 4 V. Further, a free
comparator is provided for spindle motor back emf detection. It supports a variety of applications. Also, Pb free
package is selectable (Please refer to Marking Identification).
Applications
BTL driver for CD, CD-ROM and DVD.
Features
1) Two channels are voltage-type BTL drivers for
actuators of tracking and focus. Two channels are
voltage-type BTL driver for sled and spindle
motors. It is also built-in one channel bi-direction
DC motor driver for tray.
2) Wide dynamic range [9.0V (typ.) when Vcc1=
Vcc2= 12V, at RL= 20Ω load].
3) Separating power of Vcc1 and Vcc2 is to
improve power efficiency by a low supply
voltage for tracking, focus, and spindle.
4) Level shift circuit built-in.
5) Thermal shut down circuit built-in.
6) Mute mode built-in.
7) Dual actuator drivers:
A general purpose input OP provides differential
input for signal addition. The output structure is
two power OPAMPS in bridge configuration.
8) Sled motor driver:
A general purpose input OP provides differential
input for signal addition. The output structure is
one power OPAMP in bridge configuration.
8) Spindle driver:
Single input linear BTL driver. The output
structure are two power OPAMPS in bridge
configuration.
10) Tray in-out driver:
The DC motor driver supports forward/reverse
control for tray motor.
11) 2 Built-in regulator controllers
Adjustable range 1.25V ~ 4V
12) A free comparator
For spindle motor back emf detection

Input circuit of pin6 and pin7 is designed to avoid simultaneous activation of upper and lower
output tr. ; however, in order to improve reliability, apply motor forward/reverse input once through
open mode.
We recommend time period for open longer than 10msec.
“H” side Output voltage on output voltage (VOL+, VOL-) varies depending on output control
terminal for tray (pin21). “H” side output voltage is set three times (9.2dB Typ.) VTCL(pin21). And,
“L” side output voltage is equal to output saturation voltage.
