Philips TJA1020 Data Sheet
Summary
The NXP TJA1020 is a LIN (Local Interconnect Network) transceiver IC that serves as the interface between LIN protocol controllers and the physical bus in automotive applications. The datasheet describes its capability for baud rates up to 20 Kbaud, very low electromagnetic emission, high electromagnetic immunity, passive behavior in unpowered state, integrated termination resistor for slave applications, and wake-up source recognition. It supports both normal and low slope modes for reduced EMI. Target users are automotive electronics engineers designing in-vehicle sub-networks and body electronics systems.

Frequently Asked Questions
What is the maximum baud rate supported by the TJA1020?
The TJA1020 supports a maximum baud rate of 20 Kbaud.
How is the TJA1020 protected against automotive electrical transients?
Its bus and battery pins are protected against transients per ISO7637 automotive standards.
What is the function of the INH pin on the TJA1020?
The INH pin is an active HIGH inhibit output for controlling an external voltage regulator.
What are the key differences between normal and low slope modes?
Low slope mode further lengthens the signal rise/fall times to reduce electromagnetic emission beyond normal mode.
What is the typical sleep mode current consumption?
The typical supply current on pin BAT in sleep mode is 1 μA.
