Overview
The TLD2311ELXUMA1 is a high-side LED driver IC from Infineon’s LITIX family, designed for automotive lighting applications. It features three independent constant current outputs capable of delivering up to 120 mA per channel. The device operates within an input voltage range of 5.5 V to 40 V and supports PWM dimming control. Packaged in a PG-SSOP-14-5 with exposed pad, it is AEC-Q100 qualified and rated for junction temperatures between -40°C and +150°C.
Feature Summary
- Provides three independent high-side constant current channels for precise LED regulation
- Supports pulse-width modulation (PWM) dimming for brightness control
- Integrated protection mechanisms including over-temperature and open-load detection
Applications
- Automotive exterior lighting systems such as DRLs and turn signals
- Interior ambient lighting modules requiring multi-channel control
- General-purpose LED illumination circuits in harsh environments
Procurement Notes
Verify the complete part number TLD2311ELXUMA1 against official Infineon documentation to ensure correct suffix and revision level. Confirm AEC-Q100 qualification status and RoHS compliance requirements specific to your target market regulations before finalizing procurement specifications.
Selection Notes
Select this component when designing automotive LED drivers requiring three isolated channels with linear dimming capabilities. Ensure the application voltage stays within the 5.5 V to 40 V range and that thermal management accommodates the SSOP-14 package constraints under maximum load conditions.
Part Context
This device belongs to the LITIX Basic series, optimized for cost-sensitive automotive lighting solutions. It complements other variants like the TLD2314 by offering similar functionality with specific pinout or feature configurations tailored for standard high-side driving requirements in passenger vehicle architectures.
Replacement Considerations
The TLD2326ELXUMA1 is listed as a parameter-equivalent alternative, though it is marked as obsolete. Verify functional compatibility with the TLD1310ELXUMA1 or TLD1314ELXUMA1 if sourcing new production units, ensuring pin-to-pin and electrical specification alignment.
