1.2 Description

The TLIN1028x EVM provides users with the ability to evaluate the TI TLIN1028x-Q1 family of single-channel LIN system basis chip (SBC) transceivers. The EVM allows both commander and responder mode applications to be evaluated through the use of a single jumper that connects or disconnects the external 1-kΩ pullup resistor and series diode required in commander mode from the LIN bus.

The EVM has access to the integrated, low-voltage VCC rail that provides the pull-up for RXD, and the logic level for the enable (EN) control input pins through the use of a jumper. The TLIN1028x-Q1 supports a VIH from 2 V to 5.5 V, allowing operation with a variety of microcontrollers with common IO voltage levels such as 2.5 V, 3.3 V, and 5 V. Non-populated capacitor pads are available on the TXD, RXD, and LIN pins to accommodate a variety of different tests requiring various capacitive load conditions.

If additional ESD protection is desired, a diode pad is available on the LIN bus to accommodate any SOD323 diode. A header is provided on the power and LIN bus connections to allow the EVM to be evaluated in a larger system.
