TJA1020T/CM,118 LIN bus transceiver, 5-27V, 20kb/s, SO-8

Overview The TJA1020 is the interface between the LIN master/slave protocol controller and the physical bus in a local interconnection network (LIN). It is primarily intended for in-vehicle subnets with baud rates from 2.4 to 20 kbaud.

Features General information

• Baud rate up to 20 kbaud • Very low electromagnetic emission (EME) • High electromagnetic immunity (EMI) • Low Slope mode for even further reduction of EME • Passive behavior in a de-energized state • Input level compatible with 3.3 and 5 V devices • Built-in terminator for Local Interconnect Network (LIN) slave applications • Wake-up source detection (local or remote) • Supports K-line-like functions.

Low-power management

• Very low power consumption in sleep mode with local and remote waking.

Protective measures

• Transmit data (TXD) dominant timeout function • Bus terminal and battery pin protected against transients in the automotive environment (ISO7637) • Short-circuit-proof bus terminal against battery and ground • Thermally protected.
