Description

The TLIN1039-Q1 EVM provides users with the ability to evaluate the TI TLIN1039-Q1 and TLIN1021A-Q1 single-channel, LIN transceivers in the SOT package. 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 TLIN1039-Q1 and TLIN1021A-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
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 TLIN1039-Q1 and TLIN1021A-Q1 families support 12 V automotive applications and operate with a supply voltage from 4.5 V to 36 V, plus an extended bus fault protection of ±45 V.

Furthermore, the TLIN1039-Q1 and TLIN1021A-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 MMBZ27VCL diode is populated on the LIN bus. This can be removed to test other ESD diodes as well, as it is the common SOT23 package for ESD diodes. 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.
