1 Introduction

1.1 Features

This EVM supports the following features:

  • Commander mode and Responder mode configurations
  • Terminal block and headers pins are available on all power and LIN bus connections
  • Optional VCC rail and pull-up resistors for EN input and RXD output
  • A pushbutton circuit to engage local wake on the WAKE pin (TLIN1021A-Q1)

1.2 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.

2 EVM Setup and Requirements

Use the following equipment to evaluate the performance of the TLIN1039-Q1 and TLIN1021A-Q1 devices:

  • Power supply capable of supplying the desired supply voltage. Typical LIN applications use 12 V or
    24 V, but the TLIN1039-Q1 and TLIN1021A-Q1 operate with any supply voltage from 4.5 V to 36 V. Connect this voltage across the VBAT and GND pins of either the J2, J3, or J5 connectors.
  • Power supply capable of supplying the desired IO pin voltage from 2 V to 5.5 V. Connect this voltage across the VCC and GND pins of the J6 connector.
  • If the LIN bus interface or the INH pin (TLIN1021A-Q1) is to be observed on an oscilloscope, use probes capable of tolerating voltages as large as VBAT.
  • The logic interface pins (TXD: TP6, RXD: TP7, and EN: TP5) may interface to a microcontroller, pattern generator, or logic analyzer with logic levels matching the VCC voltage.

J1 6-pin (3x2) header to observe/inject various logic signals on the U1 device

  • Pins 1,3, and 5 are all connected to GND
  • Pin 2 is connected to the RXD pin
  • Pin 4 is connected to the EN pin
  • Pin 6 is connected to the TXD pin

J2 2-pin (2x1) header for supplying or monitoring VSUP
J3 3-pin (3x1) header to observe the LIN bus and to supply VBAT
J4 2-pin (2x1) header connecting the commander mode external pull-up to the LIN bus. If shunted, U1 is in commander mode, if left open U1 is in responder mode.
J5 3-pin (3x1) header that has the same function as J3

2.1 Commander Mode

To configure the board for commander mode, place a shunt on J4 to connect the external 1-kΩ resistor and series diode to the LIN bus per the LIN specification.

2.2 Responder Mode

To configure the board for responder mode, remove the shunt on J4 to disconnect the external 1-kΩ resistor and series diode from the LIN bus per the LIN specification.

2.3 Pushbutton Wake

To use the pushbutton Wake circuit, push down on the S1 button while the device is in sleep mode to transition it back to standby mode. The WAKE function is only present on the TLIN1021A-Q1 device.
