2.2 Description

The TCAN1167EVM provides users with the ability to evaluate the TCAN1164-Q1 and TCAN1167-Q1 CAN transceivers. The only difference between these two devices is the use of pins 7 and 9. TCAN1167-Q1 uses these pins for the INH and WAKE features respectively. TCAN1164-Q1 does not have these features so the pins are left as no connects (NC).

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.

The primary digital pin signals are available through the J3 header. This allows the user to connect in their own processor to configure and control the transceiver.

The TCAN1164-Q1 and TCAN1167-Q1 support 12-V automotive applications and are operated with a single supply voltage:

  • VSUP: 5.5 V to 28 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.
