Infineon TLE8366EVXUMA1 Automotive Linear Voltage Regulator, PG-TSDSO-14 for BCMs

Infineon TLE8366EVXUMA1 Automotive Voltage Regulator Overview for B2B Vehicle Control Units

The Infineon TLE8366EVXUMA1 is a rugged, automotive-grade linear voltage regulator??engineered for B2B applications requiring consistent 3.3V power, cross-vehicle battery compatibility, and space efficiency for Automotive Electronics. It targets critical vehicle control systems: body control modules (BCMs), HVAC control units, and door lock modules. Key integrations include: fixed 3.3V output voltage (optimized for BCM microcontrollers and sensors), 4.5V?C40V wide input range (supports 12V passenger cars and 24V commercial trucks), 92% peak efficiency (minimizes power loss), built-in over-voltage (OVP), over-current (OCP), and thermal shutdown (TSD) protection, PG-TSDSO-14 (Thin Shrink Dual Small Outline, 14-pin) surface-mount package, and -40??C to +125??C operating temperature??delivering reliable power to sensitive electronics in harsh vehicle environments.

With 4.5V?C40V wide input range + 3.3V precision regulation (tuned for BCM reliability and automotive voltage variability), it balances three critical B2B needs: cross-platform compatibility (avoids separate regulators for cars/trucks), component protection (shields microcontrollers from surges), and design efficiency (fits dense PCB layouts). As part of Infineon??s automotive power management lineup??a series trusted by 130,000+ automotive electronics engineers and BCM manufacturers??it meets strict quality benchmarks: AEC-Q100 Grade 2 (1,000+ hours of stress testing), ISO 26262 ASIL-B (functional safety for vehicle controls), RoHS 3, and UL 94V-0 (package flammability).

Senior engineers at a leading fleet BCM supplier endorse it: ??This regulator powers our 24V truck BCMs. Its 40V input handles battery spikes, and 92% efficiency keeps BCMs cool??we hit 99.95% uptime and 98% fleet operator satisfaction.??

Advantages vs. Typical Alternatives

Compared to narrow-input regulators (only 12V), low-precision regulators (ruin sensor accuracy), and large-package regulators (need extra PCB space), this Infineon Voltage Regulator solves critical B2B pain points??backed by real customer feedback:

1. Better Cross-Vehicle Support Than Narrow-Input Regulators: Narrow-input (4.5V?C18V) regulators only work with 12V cars, forcing commercial OEMs to stock separate 24V regulators??adding $2.40 per unit in inventory costs and 45% more SKUs. The 4.5V?C40V range works for both. A truck BCM engineer said: ??Our old regulators needed 2 SKUs??this model needs 1. We saved $120k yearly for 50,000 units and won a $3M contract with a global truck maker that wanted a unified control solution.??

2. More Accurate Regulation Than Low-Precision Regulators: Low-precision (??5%) regulators cause BCM sensor drift (e.g., HVAC temp errors), leading to 40% more customer complaints and $200,000 yearly in service costs. The ??2% precision eliminates this. An HVAC control engineer shared: ??Our old ??5% regulators had 40% temp complaints??this ??2% model has 8%. We saved $168k in service costs and retained a $2.2M EV HVAC contract, as EV owners demand consistent climate control.??

3. Smaller Footprint Than Large-Package Regulators: DIP14 packages (19.05mm x 6.35mm) take up 35% more PCB space than PG-TSDSO-14, forcing BCMs to exceed under-dash size limits. The PG-TSDSO-14 enables miniaturization. A door module engineer confirmed: ??Our old DIP14 modules were too big for 70% of new car doors??this PG-TSDSO-14 model fits. We won a $1.8M contract with a luxury automaker, as their slim door designs require compact electronics.??

An HVAC engineer said: ??Our old ??5% regulators had 40% temp complaints??this ??2% model has 8%. We saved $168k in service costs and kept a $2.2M EV HVAC contract, as EV owners hate inconsistent heating/cooling.??

What value does the PG-TSDSO-14 package add for door lock modules?

A door module engineer said: ??Our old DIP14 modules failed 70% of fit checks??this PG-TSDSO-14 model passes all. We won a $1.8M luxury automaker contract, as their slim doors need compact electronics.??

Why is 92% efficiency important for fleet vehicle BCMs?

Fleet BCMs run 24/7??low-efficiency (84%) regulators waste 16% of power as heat, shortening lifespan by 1.8 years and increasing replacement costs. 92% efficiency cuts waste to 8%, extending life. A fleet supplier said: ??Our old 84% regulators lasted 3.2 years??this 92% model lasts 5.7 years. Replacement costs dropped by 35%, saving clients $60k yearly and growing our fleet business by 28%.??

How does AEC-Q100 Grade 2 compliance benefit off-road vehicle controls?

Off-road vehicles face -40??C (winter snow) to +125??C (desert heat)??non-compliant regulators fail in 15% of cases, causing control outages. Grade 2 tests ensure survival. An off-road engineer said: ??Our old non-compliant regulators failed 15% of the time??this Grade 2 model fails 0.3%. We retained a $1.5M off-road rental contract, as their vehicles need reliable controls in extreme terrain.??
