Circuit Considerations for TCAN337GDR

Power Supply & Operating Modes

The TCAN337GDR offers flexible operating modes for power optimization:

Normal Mode: Active transceiver operation for CAN communication[reference:61]
Silent Mode: Receiver active, transmitter disabled (TCAN337 only)[reference:62][reference:63]
Supply Voltage: Operates with VCC from 3 V to 3.6 V[reference:64]
Decoupling: Place a ceramic capacitor (0.1 µF) close to the VCC pin to minimize supply noise
Fault Output: FAULT pin (TCAN337 only) provides diagnostic output for system monitoring[reference:65][reference:66]

PCB and Signal Integrity Guidance

CAN transceiver performance depends on layout and signal routing:

Bus Termination: Proper termination resistors (120 Ω) are required at both ends of the CAN bus for impedance matching
Bus Fault Protection: ±14 V bus fault protection enables use in harsh environments[reference:67]
ESD Protection: ±25 kV HBM and ±12 kV IEC ESD protection provides system-level robustness[reference:68]
Driver Dominant Time-Out (DTO): Prevents bus lock-up in case of TXD stuck-dominant fault conditions[reference:69]
Receiver Dominant Time-Out (DTO): Protects against RXD stuck-dominant fault conditions[reference:70]
Thermal Shutdown: Built-in TSD protects the device from overtemperature conditions[reference:71]
Undervoltage Protection: UVLO on VCC ensures robust operation during power supply transients[reference:72]
Unpowered Behavior: Bus and logic pins are high impedance with no load to operating bus or application; glitch-free power up/down operation[reference:73]
Ground Plane: Use a solid ground plane to minimize noise and ensure low-inductance return paths
Verify the recommended PCB footprint from the official datasheet prior to production
