LDS8845-002-T2

Overview

The LDS8845-002-T2 is a four-output linear LED driver IC from IXYS Integrated Circuits Division. It features PWM dimming capability and delivers a constant output current of 30mA per channel with an output voltage of 6V. The device operates within a temperature range of -40°C to 85°C (TA). It is housed in a compact 16-TQFN package measuring 3x3 mm, designed for efficient power management in LED lighting applications.

Feature Summary

• Four independent output channels for driving multiple LEDs
• Supports Pulse Width Modulation (PWM) dimming control
• Linear regulation topology for stable current delivery
• Compact 16-pin TQFN surface-mount packaging

Applications

• General solid-state LED lighting systems
• Backlighting drivers for displays
• Indicator light circuits
• Low-power LED arrays requiring precise current regulation

Procurement Notes

Verify the manufacturer designation as IXYS Integrated Circuits Division, now part of Microchip Technology. Confirm the package type is 16-TQFN (3x3 mm) and the suffix indicates tape and reel packaging. Ensure the operating temperature range matches the specified -40°C to 85°C ambient limit for your application environment.

Selection Notes

Select this component when a multi-channel linear driver is required for low-current LED strings. The 30mA output rating suits standard indicator or low-brightness display LEDs. Consider the linear topology's thermal dissipation requirements relative to the input-output voltage differential. The small form factor makes it suitable for space-constrained PCB layouts.

Part Context

This device belongs to the PowerLite™ series of LED drivers, focusing on integrated solutions for lighting control. It represents IXYS's contribution to power management semiconductors before the division's integration into Microchip. The product line emphasizes simplified design through integrated regulation and dimming functions.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing circuit designs if considering alternative manufacturers offering similar 4-channel linear LED drivers with PWM support.
