Infineon TDA387250000AUMA1 Automotive LED Driver, PG-TSDSO-16 for Vehicle Lighting Systems

Infineon TDA387250000AUMA1 Automotive LED Driver Overview for B2B Vehicle Lighting Systems

The Infineon TDA387250000AUMA1 is a rugged, automotive-grade LED driver??engineered for B2B applications requiring stable constant-current power for Automotive Electronics lighting systems. It targets critical vehicle lighting: LED headlamps, tail lamps, daytime running lights (DRLs), and interior ambient lighting. Key integrations include: 500mA fixed constant current (ensures uniform LED brightness), 9V?C36V wide input range (compatible with 12V passenger cars and 24V commercial trucks), 94% peak efficiency (minimizes power loss and thermal stress), built-in over-voltage (OVP), over-current (OCP), and thermal shutdown (TSD) protection, PG-TSDSO-16 (Thin Shrink Dual Small Outline, 16-pin) surface-mount package, and -40??C to +125??C operating temperature??delivering reliable performance for LEDs in harsh automotive environments.

With 500mA constant current + 9V?C36V wide input range (tuned for LED brightness consistency and cross-vehicle compatibility), it balances three critical B2B needs: lighting reliability (avoids uneven brightness), platform flexibility (works across car/truck models), and design efficiency (fits space-constrained lighting modules). As part of Infineon??s automotive LED driver lineup??a series trusted by 118,000+ 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 lighting controls), RoHS 3, and UL 94V-0 (package flammability).

Senior engineers at a leading global automotive lighting supplier endorse it: ??This driver powers our LED headlamps. Its 500mA constant current eliminates brightness drift, and 36V input handles truck battery spikes??we hit 99.96% lighting uptime and 97% automaker satisfaction.??

Advantages vs. Typical Alternatives

Compared to narrow-input LED drivers (only 12V), low-accuracy constant-current drivers (cause brightness drift), and large-package drivers (need extra PCB space), this Infineon LED Driver solves critical B2B pain points??backed by real automotive lighting feedback:

1. Better Cross-Vehicle Support Than Narrow-Input Drivers: Narrow-input (9V?C18V) drivers only work with 12V cars, forcing commercial OEMs to stock separate 24V drivers??adding $2.70 per unit in inventory costs and 50% more SKUs. The 9V?C36V range works for both. A truck lighting engineer said: ??Our old drivers needed 2 SKUs??this model needs 1. We saved $135k yearly for 50,000 units and won a $3.5M contract with a global truck maker that wanted a unified LED lighting solution.??

2. More Consistent Brightness Than Low-Accuracy Drivers: Low-accuracy (??8%) constant-current drivers cause LED brightness mismatch (e.g., uneven headlamps), leading to 45% more customer complaints and $240,000 yearly in warranty costs. The ??3% accuracy eliminates this. A headlamp supplier shared: ??Our old ??8% drivers had 45% brightness complaints??this ??3% model has 7%. We saved $210k in warranties and retained a $2.3M luxury car headlamp contract, as buyers demand uniform lighting.??

3. Smaller Footprint Than Large-Package Drivers: DIP16 packages (19.05mm x 6.35mm) take up 40% more PCB space than PG-TSDSO-16, forcing interior lighting modules to exceed dashboard size limits. The PG-TSDSO-16 enables miniaturization. An interior lighting engineer confirmed: ??Our old DIP16 modules were too big for 65% of new car dashboards??this PG-TSDSO-16 model fits. We won a $2.1M contract with a mainstream automaker, as their slim dash designs require compact ambient lighting.??

Frequently Asked Questions (FAQ)

Why is 9V?C36V input range important for commercial truck LED lighting?

Commercial trucks use 24V batteries, which spike to 32V during jump-starts??narrow-input (18V max) drivers fail these spikes, causing LED dimming or shutdown. The 36V range protects lighting. A truck lighting engineer said: ??Our old 18V drivers caused 25% LED failures in trucks??this 36V model stops that. We saved $135k in inventory and won a $3.5M global truck contract, as fleet operators need reliable lighting during jump-starts.??

How does ??3% current accuracy improve LED headlamp performance?

LED headlamps need uniform brightness for safety??low-accuracy (??8%) drivers cause a 0.5?C1.0kcd brightness difference between left/right headlamps, leading to 45% customer complaints. ??3% accuracy limits difference to 0.2kcd. A headlamp supplier said: ??Our old ??8% drivers had 45% complaints??this ??3% model has 7%. We saved $210k in warranties and kept a $2.3M luxury car contract, as their buyers reject uneven headlamps.??

What value does the PG-TSDSO-16 package add for interior ambient lighting?

Modern car dashboards have limited space for ambient lighting??DIP16 packages take 40% more space than PG-TSDSO-16, making modules too big for 65% of new designs. PG-TSDSO-16 shrinks the module. An interior lighting engineer said: ??Our old DIP16 modules failed 65% of fit checks??this PG-TSDSO-16 model passes all. We won a $2.1M mainstream automaker contract, as their slim dashes need compact ambient lighting that doesn??t crowd other components.??

Why is 94% efficiency important for passenger car LED tail lamps?

Passenger car tail lamps are in enclosed housings??low-efficiency (86%) drivers waste 14% of power as heat, shortening LED lifespan by 2.2 years and increasing replacement costs. 94% efficiency cuts waste to 6%. A passenger car OEM said: ??Our old 86% drivers lasted 4.8 years??this 94% model lasts 8 years. Replacement costs dropped by 38%, saving $180k yearly and boosting customer satisfaction with longer-lasting tail lamps.??

How does LED open/short-circuit protection benefit fleet vehicles?

Fleet vehicles rely on functional tail lamps for safety??LED drivers without protection fail in 12% of open/short cases, causing roadside repairs and fines. This driver??s protection stops 98% of failures. A fleet lighting manager said: ??Open/short protection cut tail lamp repairs by 90%??we saved $48k yearly in roadside service and avoided $12k in safety fines. This driver became our standard for all 5,000 fleet trucks.??
