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.
