Overview
The TLD1310ELXUMA1 is a LITIX Basic 3-channel high-side LED driver IC from Infineon Technologies, designed for automotive lighting applications. It operates within a supply voltage range of 5.5 V to 40 V and delivers a constant output current of 120 mA per channel. The device features an internal boost topology to support higher load voltages up to 40 V. It is housed in a PG-SSOP-14 package with exposed pad and is qualified to AEC-Q100 standards. The operational temperature range spans from -40°C to +150°C TJ.
Feature Summary
- Integrates three independent high-side channels for precise LED current regulation
- Utilizes internal boost topology to drive loads exceeding the supply voltage
- Supports PWM dimming control for adjustable brightness levels
- Includes integrated protection mechanisms against short circuits and thermal overload
Applications
- Automotive exterior lighting systems
- LED headlamp modules
- Daytime running light circuits
- Fog lamp drivers
Procurement Notes
Verify the specific ordering suffix ELXUMA1 to confirm the reel packaging format and tape width compatibility with your pick-and-place equipment. Ensure the component meets AEC-Q100 grade requirements for your target automotive application. Cross-reference the datasheet revision date to confirm pinout and electrical characteristics match your design specifications before finalizing procurement.
Selection Notes
Select this component when a three-channel solution with high current capability is required. The internal boost converter allows driving series-connected LEDs without external inductors, simplifying PCB layout. Compare the 120 mA output current against load requirements to ensure adequate margin. Consider the SSOP-14 package size constraints relative to available board space and thermal dissipation needs.
Part Context
This part belongs to the Infineon LITIX Basic family, which provides cost-effective solutions for basic LED control functions. It complements other variants like the TLD2314ELXUMA1 by offering similar channel counts but with distinct internal switching topologies suited for different voltage headroom scenarios in automotive lighting architectures.
Replacement Considerations
The TLD2326ELXUMA1 is documented as a parameter-equivalent replacement option. Verify functional compatibility regarding the linear versus boost topology differences before substitution. Other potential substitutes include the TLD1313ELXUMA1 and TLD1314ELXUMA1; confirm pin-to-pin compatibility and electrical parameter alignment with official Infineon documentation.
