DESIGN REFERENCE

Circuit Considerations for TCAN1042HDR

Power Supply & Decoupling

The TCAN1042HDR requires proper power supply design for optimal performance:

Supply Voltage: Operates with VCC from 4.5 V to 5.5 V[reference:51][reference:52]
Decoupling: Place a ceramic capacitor (0.1 µF) close to the VCC pin to minimize supply noise
Low Standby Current: 22 µA typical standby current reduces power consumption in idle states[reference:53]
Undervoltage Protection: Built-in UVLO ensures robust operation during power supply transients[reference:54]

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 Protection: The H-model provides ±70 V bus fault protection, enabling use in harsh environments[reference:55]
ESD Protection: ±16 kV HBM and ±15 kV IEC ESD protection ensures robustness against electrostatic discharge[reference:56]
Thermal Shutdown: Built-in TSD protects the device from overtemperature conditions[reference:57]
TXD Dominant Time-Out: Prevents bus lock-up in case of TXD stuck-dominant fault conditions[reference:58]
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
