LIN 2.0/SAE-J2602 standalone transceiver TJA1021
LIN lets you easily interconnect locally applied sensors, actuators and_switches (in switch panels, door and_seat modules for example) to the CAN backbone with a standardized front end. This helps significantly reduce costs and_design-in effort for a wide range of human reaction time triggered applications, such as powered mirrors and_windows.
The rapid adoption by automotive makers of the LIN 2.0 protocol has made this cost-effective,low-speed serial communication system bus the natural choice for arbitration-free local communications. Optimized for reliable and_cost-effective LIN master_and_slave node implementations, with its sleep current consumption < 10μA and_providing IEC-61000-4-2 compliant ± 6 kV ESD protection, the TJA1021 gives you the leading-edge when creating LIN systems.
The TJA1021 is the interface between the Local Interconnect Network (LIN) master/slave protocol controller and_the physical bus in a LIN. It is primarily intended for in-vehicle sub-networks using baud rates from 1 kBd up to 20 kBd and_is LIN 2.0/SAE J2602 compliant. The TJA1021 is pin-to-pin compatible with the TJA1020 and_improved on ElectroStatic Discharge (ESD).
The transmit data stream of the protocol controller at the transmit data input (TXD) is
converted by the TJA1021 into a bus signal with optimized slew rate and_wave shaping to minimize ElectroMagnetic Emission (EME). The LIN bus output pin is pulled HIGH via an internal termination resistor. For a master_application an external resistor in series with a diode should be connected between pin INH or pin VBAT and_pin LIN. The receiver detects the data stream at the LIN bus input pin and_transfers it via pin RXD to the microcontroller.
In sleep mode the power consumption of the TJA1021 is very low. In failure modes the
power consumption is reduced to a minimum.
