## Core Features & Advantages
The TH8056KDC-AAA-014-RE delivers exceptional performance for demanding single-wire CAN communication in automotive and industrial environments.
– **Primary Function**: Enhanced Single Wire CAN Transceiver compliant with GMW3089 V2.4 and SAE J2411 specifications, designed for Class B in-vehicle network communications.
– **Key Advantages**:
– **Ultra-Low Sleep Current**: Only 30 µA typical in sleep mode — independent of CAN bus voltage — making it ideal for always-connected automotive ECU applications where battery drain must be minimized.
– **Wide Operating Voltage Range**: 5V to 26.5V supply range with robust protection against load dump, jump start, and short circuit conditions, fully compatible with 12V automotive electrical systems.
– **Four Operating Modes**: Sleep, Normal, High-Voltage Wake-Up (HVWU), and High-Speed — selectable via Mode 0/Mode 1 pins — providing flexible power management and data rate trade-offs for different vehicle operating states.
– **Output Wave Shaping**: Integrated output waveform shaping in Normal and HVWU modes minimizes radiated emissions (RFI), reducing system-level EMC compliance effort without external filtering components.
– **Comprehensive Protection Suite**: Under-voltage lockout, TxD dominant time-out, bus ringing blanking, loss-of-ground protection with extremely low leakage (typ. 20 µA at 27V/125°C), and thermal overload shutdown.
– **14-Pin Thermally Enhanced Package**: The SOIC-14 variant provides additional thermal dissipation and exposed pins for enhanced robustness compared to the 8-pin version, suitable for higher-power or harsher thermal environments.
– **AEC-Q100 Qualified**: Meets automotive-grade reliability requirements, validated for operation across the full -40°C to +125°C temperature range.
## Typical Application Scenarios
– **Industry**: Automotive, Industrial Automation, Commercial Vehicles
– **Equipment**: Automotive ECU modules, gateway controllers, body electronics, diagnostic tool interfaces, industrial CAN bus nodes
– **Use Cases**:
– **GM-LAN Single Wire CAN Networks**: Directly compliant with GMW3089 V2.4 for GM-LAN Class B communication in platforms such as GMT-900, Epsilon-2, and Global-A — the de facto standard for in-vehicle single-wire CAN.
– **Automotive Body Electronics**: Connect door modules, seat controllers, lighting systems, and HVAC units via a single-wire bus, reducing wiring harness weight and cost compared to dual-wire CAN.
– **Automotive Diagnostic Tool Interface**: Use High-Speed mode (up to 100 kbps) for faster ECU programming and diagnostic data download at service stations, with Normal mode (33.33 kbps) for routine operation.
