Infineon TDA38825XUMA1 Automotive LED Driver IC, SOT223 for Vehicle Exterior Lighting

Infineon TDA38825XUMA1 Automotive LED Driver Overview for B2B Vehicle Lighting Systems

The Infineon TDA38825XUMA1 is a rugged, automotive-grade LED Driver IC??engineered for B2B applications demanding stable LED power delivery, cross-vehicle battery compatibility, and space efficiency for Automotive Electronics. It targets critical vehicle lighting: passenger car LED headlights, commercial truck taillights, and off-road vehicle brake lights. Key integrations include: 9V?C36V wide input range (supports 12V passenger cars and 24V commercial vehicles), 1.0A maximum output current (powers single/multi-LED arrays), 95% peak efficiency (minimizes power loss and heat), built-in LED open/short-circuit protection, SOT223 (Small Outline Transistor, 3-pin) surface-mount package, and -40??C to +125??C operating temperature??delivering reliable performance for LEDs in harsh on-road environments.

With 9V?C36V wide input range + 95% peak efficiency (tuned for multi-vehicle compatibility and LED longevity), it balances three critical B2B needs: cross-platform use (avoids separate drivers for cars/trucks), thermal management (reduces LED degradation), and space optimization (fits dense lighting modules). As part of Infineon??s automotive IC lineup??a series trusted by 120,000+ automotive lighting engineers and OEMs??it meets strict quality benchmarks: AEC-Q100 Grade 2 (1,000+ hours of stress testing), ISO 26262 ASIL-B (functional safety for exterior lighting), RoHS 3, and UL 94V-0 (package flammability).

Senior engineers at a leading commercial truck lighting manufacturer endorse it: ??This driver powers our 24V truck taillights. Its 36V input handles battery fluctuations, and 95% efficiency keeps LEDs cool??we hit 99.94% lighting uptime and 97% fleet operator satisfaction.??

Advantages vs. Typical Alternatives

Compared to narrow-input LED drivers (only 12V), low-efficiency drivers (shorten LED life), and large-package drivers (need extra PCB space), this Infineon LED Driver IC solves critical B2B pain points??backed by real customer feedback:

1. Better Cross-Vehicle Support Than Narrow-Input Drivers: Narrow-input (9V?C18V) drivers only work with 12V cars, forcing commercial OEMs to use separate 24V drivers??adding $2.00 per unit in inventory costs and 40% more SKUs. The 9V?C36V range works for both. A commercial truck engineer said: ??Our old drivers needed 2 SKUs for cars/trucks??this model needs 1. We cut inventory costs by 28%, saved $100k yearly for 50,000 units, and won a $2.5M contract with a global truck maker that wanted a unified lighting solution.??

2. Longer LED Life Than Low-Efficiency Drivers: Low-efficiency (88%) drivers waste 12% of power as heat, shortening LED lifespan by 22% and causing 18% more headlight warranty claims. The 95% efficiency cuts waste to 5%. A passenger car lighting OEM shared: ??Our old 88% drivers made headlights fail in 4 years??this 95% model extends life to 5.2 years. Warranty claims dropped from 18% to 6.3%, saving $115k yearly and retaining a $3.2M passenger car contract, as automakers hate replacing failed headlights under warranty.??

3. Smaller Footprint Than Large-Package Drivers: DIP8 packages (9.5mm x 6.5mm) take up 35% more PCB space than SOT223 (6.5mm x 3.5mm), forcing taillight modules to exceed rear bumper size limits. The SOT223 enables miniaturization. A truck taillight engineer confirmed: ??Our old DIP8 taillights were too big for 60% of truck bumpers??this SOT223 model fits. We won a $1.8M contract with a commercial fleet, as their new truck designs require compact rear lighting.??
