The TLIN2029EVM provides users with the ability to evaluate TI’s TLINx029A-Q1 family of single-channel, LIN 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 a low-voltage VCC rail that provides the voltage to the pullup resistors on the received data (RXD) open-drain output, and enable (EN) control input pins. The TLIN2029-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 and RXD pins to accommodate a variety of different tests requiring various capacitive load conditions.

The TLIN2029A-Q1 supports both 12 V and 24 V automotive applications and is operated with a supply voltage from 4 V to 48 V, plus an extended bus fault protection of ±60 V. Use the EVM to evaluate the TLIN1029A-Q1 device for 12-V automotive applications by replacing the TLIN2029A-Q1 with a TLIN1029A-Q1 transceiver.

Furthermore, the TLINx029A-Q1 transceivers include internally-protected bus terminals with greater than ±8-kV HBM and IEC ESD protection levels. If additional ESD protection is desired, a non-populated diode pad is available on the LIN bus to accommodate any SOD323 diode. Both headers and wire-terminals are provided on the power and LIN bus connections to allow the EVM to be evaluated in a larger system while still allowing for test equipment to be connected to the signals under test.
