Overview
The LV8282PV-MPB-H is a system motor driver IC from onsemi, designed for CD/DVD player systems. It integrates four BTL-type output channels to drive SLED and LOADING mechanisms using a 4-output, 5-control input configuration. The device supports variable regulator control via an external NPN transistor and includes an internal 5V regulator. Key features include thermal shutdown protection with signal output, charge pump integration, and selectable reference voltage modes during loading operations.
Feature Summary
- Integrates four BTL-type output channels for SLED and LOADING mechanism control
- Supports selectable control reference voltage between internal mode and external VREF input
- Includes variable regulator control circuit utilizing an external NPN transistor
- Features thermal shutdown protection with dedicated signal output pin
Applications
- CD/DVD-ROM/RW system drivers
- Optical disc drive SLED actuators
- Optical disc drive LOADING mechanisms
Procurement Notes
Verify component authenticity through authorized onsemi distributors or direct manufacturer channels. Confirm the specific MPB-H suffix matches design requirements. Check for End-of-Life (EOL) status notifications as discontinuance may affect long-term availability. Ensure compliance with RoHS and REACH regulations relevant to the target market.
Selection Notes
Evaluate compatibility with optical drive mechanical loads requiring BTL drive topology. Assess thermal management needs given the integrated TSD feature. Verify that the available control inputs align with system logic levels. Consider the variable regulator capability if external power conditioning is required for the load.
Part Context
This component belongs to the LV8282 series of system drivers specialized for optical storage devices. It consolidates power amplification and control logic into a single chip, reducing board space compared to discrete solutions. The series is characterized by linear MOS technology providing wide dynamic range operation for precise actuator control.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Consult onsemi technical support for current alternative recommendations due to potential product lifecycle changes.
