The AM5888S 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 1.5V to 4 V. It supports a 

variety of applications. Also, Pb free package is selectable (Please refer to Marking Identification). 

 

 

BTL driver for CD, CD-ROM and DVD.   

 

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 R

L

= 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. 

9)   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 1.5V ~ 4V

The AT24C01A/02/04/08A/16A provides 1024/2048/4096/8192/16384 bits of serial
electrically erasable and programmable read-only memory (EEPROM) organized as
128/256/512/1024/2048 words of 8 bits each. The device is optimized for use in many
automotive applications where low-power and low-voltage operation are essential.
The AT24C01A/02/04/08A/16A is available in space-saving 8-lead PDIP, 8-lead
JEDEC SOIC, and 8-lead TSSOP packages and is accessed via a two-wire serial
interface. In addition, the entire family is available in 2.7V (2.7V to 5.5V) versions.
