LTPCBA Automotive Tailgate Motor PCBA

In the automotive smart upgrade sector, power tailgate systems demand core control components that meet stringent requirements for reliability, precision, and automotive compliance. As a specialized manufacturer in automotive-grade PCBA solutions, LTPCBA presents its Tailgate Motor PCBA — delivering precise current control, stable signal output, and automotive-grade manufacturing standards to serve as the core “power center” for family vehicle tailgate systems.

1. Functional Positioning: Precision Drive & Closed-Loop Control

This PCBA is built around “power drive + signal feedback” to ensure reliable performance:

Precise Motor Control:

Supports DC 12V 5A brushed motor drive** with stall current up to 33.7A, delivering strong and stable power for tailgate operation. Maintains consistent performance under variable loads — such as winter freezing or temporary obstruction.

Real-Time Signal Feedback:  

Equipped with dual-channel HALL sensor outputs for real-time monitoring of motor speed and position. Enables closed-loop control to ensure smooth, accurate tailgate movement — preventing issues like jamming or abnormal noise caused by motor misalignment.

2. Application Focus: Tailored for Family Vehicle Tailgates

Designed specifically for cars, SUVs, and family MPVs, this PCBA serves as a core control component in the aftermarket, providing seamless “one-touch power opening” experiences. It acts as an intelligent hub connecting the original vehicle circuit to the power tailgate motor, supporting easy installation and reliable upgrade solutions.

3. Component Design & Layout: Optimized for Performance & Compliance

The PCBA layout reflects LTPCBA’s focus on automotive standards, signal integrity, and space efficiency:

Automotive-Grade Components:

Utilizes internationally certified **HALL sensors** with excellent temperature stability and EMI resistance, ensuring accurate and continuous signal output for reliable closed-loop control.

-Compact & Anti-Interference Layout:  

Features a compact circular design that fits limited spaces in tailgate assemblies. Implements physical separation between the power drive circuit and HALL signal circuits to minimize EMI and maintain signal purity.

– High-Reliability Connection: 

Includes multi-color high-flexibility cables with reinforced solder joints for superior vibration and bend resistance — ideal for challenging automotive environments.

4. Manufacturing Process: Automotive-Grade Reliability

LTPCBA ensures robustness through automotive-compliant manufacturing:

– EMC Compliance Validation:  

Passes automotive **EMC tests** for stable operation in complex electromagnetic environments — preventing control issues caused by interference.

– Precision Assembly & Validation:

Applies **±0.02mm SMT placement accuracy** for HALL sensors and power components. Each unit undergoes **-40℃ to 125℃ thermal cycling, stall current endurance, and vibration tests** to ensure extreme-condition reliability.

– Environmental Protection:  

Optional **automotive-grade conformal coating** enhances resistance to moisture, dust, and corrosion — extending service life for long-term dependable operation.

Conclusion

LTPCBA’s Tailgate Motor PCBA sets a new standard for reliability, precision, and compatibility in family vehicle power tailgate systems. As a trusted PCBA manufacturer, LTPCBA remains committed to innovation and quality in automotive electronics — delivering stable, smart, and efficient core components that support the ongoing evolution of vehicle intelligence.
