CAT310W-T1

Overview

The CAT310W-T1 is a 10-channel automotive LED display driver manufactured by onsemi. It features an external linear current regulation architecture with a maximum output current rating of 50mA per channel. The device operates within a supply voltage range compatible with standard automotive systems and utilizes a 20-SOIC surface-mount package. Designed for high reliability, it meets AEC-Q100 qualification standards for automotive applications, ensuring stable performance in demanding environments.

Feature Summary

• Provides independent current control for ten distinct LED channels
• Utilizes external linear regulation to minimize electromagnetic interference
• Qualified for automotive grade operation under strict environmental conditions

Applications

• Automotive instrument cluster displays
• Multi-zone interior ambient lighting systems
• External vehicle status indicator arrays

Procurement Notes

Verify the specific suffix 'T1' against official datasheets to confirm tape-and-reel packaging requirements. Ensure compatibility with existing PCB footprints for the 20-SOIC package. Confirm that the design supports the necessary external components for linear current regulation as specified in the electrical characteristics section.

Selection Notes

Select this component when precise, low-noise current regulation is required for multiple LEDs without complex digital communication overhead. It is suitable for designs prioritizing simplicity and robustness over programmable brightness levels. Evaluate thermal dissipation capabilities of the external resistors relative to the 50mA output capability.

Part Context

This part belongs to the CAT310W family of LED drivers from onsemi, specifically tailored for automotive display applications.
