The LIN Click is a Click board™ that features the TLE7259-3GE, a LIN transceiver from Infineon Technologies, with integrated wake-up and protection features. The combination of Peripheral and Controller node in LIN systems, the LIN Click can be used for automotive applications: body controllers and gateway modules, switch panels, wiper or window lift modules, door and seat control modules and engine management units.
The LIN Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
LIN or Local Interconnect Network is a protocol used for communicating between components in vehicles. These days cars have hundreds of sensor applications to measure things like temperature, pressure, air flow, speed, etc. All these applications need to communicate with the main system. The LIN Click is based on the TLE7259-3GE, LIN transceiver from Infineon Technologies with integrated wake-up and protection features. It is designed for in-vehicle networks using data transmission and it operates as a bus driver between the protocol controller and the physical bus of the LIN network. Compliant to all LIN standards and with a wide operational supply range the TLE7259-3GE can be used in all automotive applications.It can be used with CAN (Controller Area Network), but LIN is more cost-effective for simple sensor networks in vehicles.
In Sleep-mode the TLE7259-3GE draws typically less than 8 μA of quiescent current while still being able to wake up when detecting LIN bus traffic and a local wake up signals. The very low leakage current on the BUS pin makes the TLE7259-3 especially suitable for partially supplied networks. Based on the Infineon Smart Power Technology SPT®, the TLE7259-3GE provides excellent ESD Robustness and a very high electromagnetic compliance (EMC). The TLE7259-3GE reaches very low levels of electromagnetic emission within a broad frequency range, independent from the battery voltage. The TLE7259-3GE and the Infineon SPT® technology are AEC qualified and tailored to withstand the harsh condition of the automotive environment.
The LIN Click can be configure for controller node applications or for peripheral node applications, every LIN network consists of a controller node and one or more peripheral nodes. The LIN Click communicates with the MCU by using the UART RX and TX signals.RX and TX signals are also routed to the header on the edge of the Click board™ so they can be used independently of the mikroBUS™ socket. Its most important features are the fact that it is a single-wire LIN transceiver for transmission rates up to 20 kbps and it is compliant to ISO 17987-4 and LIN Specification 2.2A. It has a very low current consumption in sleep mode with wake-up functions and it is digital I/O levels compatible with 3.3 V and 5 V microcontrollers. It is optimized for high electromagnetic compatibility (EMC); Very low emission and high immunity to interference.
The TLE7259-3GE has 3 major operation modes:
The LIN Click has a Terminal Block connector for LIN communication, LIN bus power supply Vs, LIN bus input / output data line and LIN bus ground GND .
The LIN Click, due to its key features and on-board modules, can be used for various automotive applications including body controllers and gateway modules, switch panels, wiper or window lift modules, door and seat control modules and engine management units.
