Dual LIN 2.2A/SAE J2602 transceiver

Rev. 3 — 24 May 2018

Product data sheet

1. General description

The TJA1022 is a dual LIN transceiver that provides the interface between a Local

Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN

network. It is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd

and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 (12 V LIN)

and SAE J2602. The TJA1022T and TJA1022TK (SO14/HVSON14 packages) are pin

compatible with the TJA1020, TJA1021, TJA1027 and TJA1029; the TJA1022HG

(DHVQFN24 package) is pin compatible with the TJA1024 (see Section 18). The

TJA1022, TJA1024, TJA1027 and TJA1029 are software compatible.

The transmit data streams generated by the protocol controller are converted by the

TJA1022 into optimized bus signals shaped to minimize ElectroMagnetic Emissions

(EME). The LIN bus output pins are pulled HIGH via internal termination resistors. For a

master application, an external resistor in series with a diode should be connected

between pin V_BATand each of the LIN pins. The receivers detect receive data streams on

the LIN bus input pins and transfer them via pins RXD1 and RXD2 to the microcontroller.

Power consumption is very low when both transceivers are in Sleep mode. However, the

TJA1022 can still be woken up via pins LIN1/LIN2 and SLP1_N/SLP2_N.
