... In normal transceiver operation the TJA1020 can be switched in the normal slope mode or the low slope mode. In the low slope mode the TJA1020 lengthens the rise and fall slopes of the LIN bus signal, thus further reducing the already very low emission in normal slope mode. ...

... Interconnect Network (LIN). The LIN transceiver is optimized for the maximum specified LIN transmission speed of 20 Kbaud providing optimum EMC performance due to wave shaping of the LIN output. Operating modes The TJA1020 provides two modes of normal operation, one intermediate mode and one very low power mode. Figure 3 shows the state diagram. handbook, full pagewidth ...

... The low slope mode is entered during the positive edge on NSLP while pin TXD is already pulled LOW. Sleep mode This mode is the most power saving mode of the TJA1020 and the default state after power-up (first battery supply). Despite its extreme low current consumption, the TJA1020 can still be waken up remotely via pin LIN, or waken up locally via pin NWAKE, or activated directly via pin NSLP ...

... LOW-to-HIGH transition on pin TXD. In the event of a short-circuit to ground on pin TXD, the transmitter will be disabled. Wake-up There are three ways to wake-up a TJA1020 which is in sleep mode: 1. Remote wake-up via a dominant bus state 2. Local wake-up via a negative edge at pin NWAKE 3 ...

... NSLP. This is useful for applications with a continuously powered microcontroller. Wake-up source recognition The TJA1020 can distinguish between a local wake-up request on pin NWAKE and a remote wake-up request via a dominant bus state. The wake-up source flag is set in case the wake-up request was a local one. The wake-up source can be read on pin TXD in the standby mode ...
