• Very low current consumption in local sleep mode and remote wakeup. LIN transceiver TJA1020T/CM

Protection? Transmit Data (TXD) Master Timeout Function Protects Bus Termination and Battery Pin Transients in Automotive Environments (ISO7637)

• Short circuit protection of bus terminal to battery and ground • Thermal protection. General description TJA1020 is an interface between LIN

A master/slave protocol controller and a physical bus in a Local Interconnect Network (LIN). Its main purpose is the LIN transceiver TJA1020T/CM

Use baud rates from 2.4 to 20 kbaud for on-board subnetworks.

TJA1020 can distinguish local wake-up

request on pin NWAKE and remote wakeup request

Master bus status. wakeup source flag set

If the wakeup request is a local request. get up

In standby mode, the source code can be read on pin TXD. if a

TXD is the main timeout function

A "TXD dominant timeout" timer circuit prevents bus
