What’s New in Ecotron’s Next-Gen TCU

Ecotron’s Transmission Control Units (TCUs) are designed to optimize electric vehicle performance through intelligent gear shifting, torque coordination, and energy management.

With the release of the ET82367A, we’ve taken a major step forward, enhancing performance, robustness, and integration for next-generation vehicle architectures.

🔍 Key Differences at a Glance

What Makes ET82367A Different?

1. Domain Controller Integration

Unlike the ET22367A, the ET82367Ais designed as a power domain controller, integrating both VCU and TCU functionality.

• Reduced system latency
• Lower system cost
• Improved coordination between motor and transmission
• Better energy efficiency

2. Higher Power Capability

The ET82367A introduces high-current actuation capability:

• 4 H-Bridge outputs
• Up to 50A peak current
• Enables direct control of actuators and motors

Ideal for more demanding transmission systems and electrified platforms.

3. Expanded I/O & Signal Capability

Compared to ET22367A:

• More analog inputs (18 vs 14)
• More digital inputs (22 vs 20)
• Increased high-side outputs (18 vs 10)
• More 5V outputs (7 vs 4)

➡️ This allows greater system flexibility and reduces external hardware.

4. Built-In Intelligence & Connectivity

ET82367A supports:

• OTA updates
• Remote diagnostics
• Telematics integration
• Gateway functionality

➡️ Ready for software-defined vehicles

5. Improved Robustness

• IP67 protection (dust + water resistant)
• Wide operating range: 9–32V, -40°C to 85°C
• Die-cast aluminum housing

➡️ Designed for harsh automotive environments

6. Built-In Sensors

• Integrated 6-axis gyroscope (standard)
• No need for external IMU

➡️ Reduces BOM cost and system complexity

When to Choose Each

Choose ET82367A if:

• You are building next-gen EV platforms
• You want VCU + TCU integration
• You need high current actuation
• You require OTA / connectivity features
• You want to reduce system complexity

Choose ET22367A if:

• You need Ethernet connectivity
• You prefer a traditional separated architecture
• Your application has lower integration requirements

Overall, the ET82367A represents a shift toward centralized, intelligent, and software-defined vehicle control, while the ET22367A remains a reliable solution for more traditional architectures.
