This post explains for the Motor Driver.
The Part Number is CD5888CB.
The function of this semiconductor is 5-channel motor driver.
The package is HSOP 28 Pin Type
Manufacturer: Wuxi China Resources Silicone Microelectronics
The CD5888CB is a 5-channel BTL driver IC for CD-ROM and DVD players for motor and drive power drive circuit built-in three independent precision voltage regulator adjustable range from 1.5V to 4V support a variety of applications the way.
A 5-channel BTL (Bridge-Tied Load) motor driver is an integrated circuit (IC) or module designed to control and drive multiple DC motors or other loads, typically in robotics, automation, and mechatronic applications. The term “Bridge-Tied Load” refers to the configuration used to drive motors, where the load (the motor) is connected between two outputs of an H-bridge arrangement.
1. Separate power supplies VCC1 and VCC2 can
2. Improve power efficiency by providing low voltage for tracking, focusing and spindle
