Introduction

YD5888 is a 5-channel BTL driver IC designed for motor and actuator drive circuits in CD, CD-ROM, and DVD players. The device integrates three independent precision voltage regulators with an adjustable range of 1.5V to 4V, supporting multiple application configurations.

Features

• Two BTL drivers for tracking and focus actuators; two BTL drivers for feed and spindle motors; one bidirectional driver for loading motor
• Dynamic range: 9V (typical: VCC1 = VCC2 = 12V, RL = 20Ω)
• Separate supplies VCC1 and VCC2 support low-voltage operation via tracking, focus, and spindle to improve power efficiency
• Built-in level shift circuit
• Built-in thermal shutdown circuit
• Built-in mute circuit
• Feed motor driver and two actuator drivers: universal op-amp at input for flexible signal handling; output stage consists of bridge power amplifier
• Spindle motor driver: single-ended linear input; output stage consists of bridge power amplifier
• Loading motor driver: DC motor driver supporting disc load/eject
• Three built-in voltage regulators: adjustable range 1.5V~4V
• Package: HSOP28

Applications

• CD player
• CD-ROM player
• DVD player
