Overview
The MX879RTR is an 8-channel LED lighting driver IC manufactured by IXYS Integrated Circuits. It features a 60V load voltage rating and operates within a temperature range of -40°C to +85°C. The device utilizes a 28-QFN (5x5) package with exposed pad for surface mount installation. It supports SPI and parallel interfaces for control. The component is classified as a high-voltage switch and power driver, designed for driving multiple loads in lighting applications.
Feature Summary
- Provides eight independent output channels for load driving
- Supports serial peripheral interface and parallel data input
- Features open-drain output configuration for flexible interfacing
- Operates reliably across extended industrial temperature ranges
Applications
- LED lighting systems requiring multi-channel control
- Relay driver circuits in industrial automation
- General purpose high-voltage load switching
- Electronic ballast drivers for discharge lamps
Procurement Notes
Verify current availability status as the component may be discontinued or have limited stock. Confirm package type matches design requirements. Check for alternative sources if original manufacturer supply is unavailable. Ensure compliance with RoHS directives for intended market. Validate pinout compatibility during integration planning.
Selection Notes
Consider the 60V maximum load voltage when selecting for specific application loads. Evaluate interface requirements against available system controllers supporting SPI or parallel protocols. Assess thermal management needs given the QFN package and operating temperature range. Compare channel count against system complexity to ensure optimal resource utilization.
Part Context
This part belongs to the MX879 series of 8-channel drivers from IXYS. It shares functional similarities with MX877 and MX878 variants but differs in output stage configuration. The series targets compact lighting and relay control solutions requiring high voltage tolerance and integrated drive capabilities in small form factors.
Replacement Considerations
MX879R is a tube-packaged variant of the same functional device. MX878RTR offers similar channel count but with push-pull outputs instead of open-drain. Verify electrical characteristics and interface compatibility before substitution.
