Overview
The TLD1311ELXUMA1 is a LITIX Basic LED lighting driver IC from Infineon Technologies, designed for automotive applications. It features three high-side current source channels with an integrated boost topology to drive LEDs efficiently. The device supports PWM control and delivers a constant output current of 120 mA per channel. It operates within a supply voltage range of 5.5 V to 40 V and withstands output voltages up to 40 V. Packaged in a SSOP-14 format, it is qualified to AEC-Q100 standards and functions reliably across temperatures from -40°C to +150°C.
Feature Summary
- Integrates three independent high-side output stages optimized for driving LEDs with constant current sources.
- Features an internal boost topology to manage LED forward voltage requirements efficiently.
- Supports precise brightness regulation through external PWM control signals.
Applications
- Automotive interior ambient lighting systems
- Vehicle exterior illumination modules
- General LED matrix driving circuits
Procurement Notes
Verify the specific ordering suffix 'XUMA1' corresponds to the required tape-and-reel packaging configuration. Confirm that the SSOP-14 package dimensions align with your PCB footprint requirements. Ensure the component meets AEC-Q100 qualification standards for your intended automotive application environment.
Selection Notes
Select this component when a three-channel solution with integrated boost functionality is required. It is suitable for designs needing 120 mA per channel without external power transistors. Consider alternative models if higher current capacity or different topologies like buck are necessary.
Part Context
This part belongs to the TLD131x family of LITIX Basic drivers. It shares architectural similarities with the TLD1310EL but differs in specific electrical characteristics and feature sets. The series focuses on providing robust, high-side driving capabilities for multi-channel LED arrays in demanding environments.
Replacement Considerations
The TLD1310ELXUMA1 is a related variant within the same product family. Verify compatibility regarding specific current ratings and protection features before substitution.
