This EVM supports the following features:

• Standard and split termination on the CAN bus.
• Footprints for filter capacitors, common-mode choke, and TVS diode for CAN bus protection from RF noise and transient pulses.
• DSUB9 connector with the CAN bus signals, VBAT, and GND for typical automotive cable harness connections.
• All digital signals for configuration and control brought out to a header for easy access.
• Pushbutton WAKE circuit for easy local wake.
• Monitoring points for CAN bus common-mode.
• Option to supply VIO with integrated LDO on the TCAN11625-Q1 and TCAN11623-Q1.
• Transceiver status indicator LED for monitoring fault conditions.

The TCAN1162EVM provides users with the ability to evaluate the TCAN1162-Q1, TCAN11623-Q1, and TCAN11625-Q1 CAN transceivers. The only difference between these three devices is the integrated LDO supply feature. TCAN1162-Q1 has an integrated LDO to supply the CAN bus from VSUP, but no output, while TCAN11623-Q1 has a 3.3V integrated LDO output, and TCAN11625-Q1 has a 5V integrated LDO output.

The EVM allows for two termination schemes through a single jumper to select between just split termination configuration, or split with 120-Ω resistor as well.

All digital pin signals as well as VIO are available through the J11 header. This allows the user to connect in their own processor to configure and control the TCAN1145 device. The TCAN1162 family of devices support IO levels from 1.8 V to 5 V, allowing operation with a variety of processors with common IO voltage levels.

The TCAN1162 family supports 12-V automotive applications and is operated with three supply voltages:

• VSUP: 5 V to 28 V
• VIO: 1.71 V to 5.5 V

The CAN bus also has extended fault protection range of ±58 V. Along with a wide bus fault protection range, there are also footprints for a common-mode choke, TVS diode for ESD protection, and capacitors for further EMC protection or signal conditioning if needed. A DSUB9 connector is included to allow the evaluation and use of the CAN bus in larger systems.

An onboard microprocessor is available to monitor and control the device through SPI ports. A GUI has been written and is available on the web to easily perform different tasks and guide the user through using the different features of the TCAN114X family.
