Overview
The LA6531-E is a dual-channel bridge-tied load (BTL) driver manufactured by onsemi, designed for compact disc pickup actuation. It features a wide operating voltage range of 4 to 15 V and delivers a maximum output current of 0.7 A per channel. The device incorporates low input bias current characteristics and includes a muting function that disables all four amplifier outputs and the buffer amplifier when activated.
Feature Summary
- Dual-channel BTL driver architecture optimized for CD pickup actuation
- Wide operating voltage range supporting 4 V to 15 V systems
- High output current capability up to 0.7 A per channel
- Integrated muting mode that turns off all amplifier and buffer outputs
Applications
- Compact disc pickup actuation
- CD-ROM drive mechanisms
- Optical storage device motor control
Procurement Notes
Verify the specific suffix E against official onsemi documentation to confirm exact electrical tolerances and package variations. Ensure compatibility with existing system voltage ranges and thermal requirements before procurement. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent device damage during operation.
Selection Notes
Select this component for applications requiring precise optical pickup movement in compact disc systems. The dual-channel BTL configuration allows efficient driving of voice coil actuators. Consider the 0.7 A current limit and 4-15 V supply range when designing the power stage. Verify thermal dissipation capabilities within the intended enclosure environment.
Part Context
This part belongs to the LA653x series of audio and actuator drivers from onsemi. It is specifically engineered for optical media players, distinguishing it from general-purpose audio amplifiers. The design focuses on low noise and high precision for mechanical actuation rather than high-fidelity sound reproduction.
Replacement Considerations
The LA6530 serves as a related variant within the same family. Note that the LA6530 differs in its muting behavior, where only the amplifier outputs are disabled while the buffer may remain active. Verify functional equivalence regarding the buffer amplifier state when substituting.
