Instructions for Using TJA1021T/10
Power Supply:
- Connect the VCC pin to a power supply within the range of 3.0V to 5.5V.
- Ensure the power supply is stable and has sufficient current capacity.
Ground Connection:
- Connect the GND pin to a common ground reference.
CAN Bus Connections:
- Connect the CANH and CANL pins to the CAN bus lines.
- Ensure the CAN bus lines are terminated with a 120Ω resistor at both ends of the bus.
Sleep Mode:
- To enter sleep mode, set the STBY pin to a high state (VCC).
- To exit sleep mode, set the STBY pin to a low state (GND).
Data Transmission:
- The TJA1021T/10 supports data rates up to 2 Mbit/s.
- Ensure the data signals on the TXD and RXD pins are within the specified voltage levels.
Overvoltage Protection:
- The device is protected against overvoltages up to 40V.
- However, avoid exposing the device to voltages above this limit to prevent damage.
ESD Protection:
- The device has an ESD rating of 4000V (Human Body Model).
- Handle the device with care to avoid static discharge.
Temperature Considerations:
- The operating temperature range is from -40°C to 125°C.
- Store the device in an environment with temperatures between -65°C and 150°C.
Mounting and Handling:
- Follow standard surface mount technology (SMT) procedures for mounting the device.
- Use appropriate soldering techniques to ensure reliable connections.
Testing and Validation:
- After assembly, perform functional tests to ensure the device is operating correctly.
- Verify the CAN bus communication by sending and receiving data packets.
For detailed application notes and further information, refer to the datasheet provided by the manufacturer.
