TJA1029T: LIN 2.2A/SAE J2602 transceiver with TXD dominant timeout
The TJA1029 is the interface between the 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 and SAE J2602. The TJA1029 is pin-compatible with the
TJA1020, TJA1021, TJA1022 and TJA1027.
The protocol controller generates the transmit data stream. The TJA1029 converts the
data stream into an optimized bus signal shaped to minimize ElectroMagnetic Emissions
(EME). The LIN bus output pin is pulled HIGH via an internal termination resistor. For a
master application, connect an external resistor in series with a diode between pin VBAT
and pin LIN. The receiver detects a receive data stream on the LIN bus input pin and
transfers it via pin RXD to the microcontroller.
Power consumption is very low in Sleep mode. However, the TJA1029 can still be woken
up via pins LIN and SLP_N. An integrated TXD dominant time-out function prevents the
bus being driven to a permanent dominant state.
- Very high ElectroMagnetic Immunity (EMI)
- Very high ESD robustness: ±8 kV according to IEC 61000-4-2 for pins LIN and VBAT
- Bus terminal and battery pin protected against transients in the automotive
environment (ISO 7637)
- Bus terminal short-circuit proof to battery and ground
- Thermally protected
- Initial TXD dominant check when switching to Normal mode
- TXD dominant time-out function
