4.1

4.2

Normal Mode

This is the normal transmitting and receiving mode of the LIN Interface, in accordance with LIN specification 2.x. The V_CC

voltage regulator operates with a 3.3V/5V output voltage, with a low tolerance of ±2% and a maximum output current of

85mA.

If an undervoltage condition occurs, NRES is switched to low and the IC changes its state to fail-safe mode.

Silent Mode

A falling edge at EN while TXD is high switches the IC into silent mode. The TXD Signal has to be logic high during the mode

select window (Figure 4-2 on page 6). The transmission path is disabled in silent mode. The overall supply current from V_Batt

is a combination of the I_VSsi= 57µA plus the V_CCregulator output current I_VCC

In silent mode the internal slave termination between pin LIN and pin VS is disabled, and only a weak pull-up current

(typically 10µA) between pin LIN and pin VS is present. The silent mode can be activated independently from the current

level on pin LIN.

If an undervoltage condition occurs, NRES is switched to low and the IC changes its state to fail-safe mode.

A voltage less than the LIN Pre-wake detection V_LINLat pin LIN activates the internal LIN receiver and switches on the

internal slave termination between the LIN pin and the VS pin.

A falling edge at the LIN pin followed by a dominant bus level maintained for a certain time period (> t_bus) and the following

rising edge at pin LIN (see Figure 4-3 on page 7) results in a remote wake-up request.

The device switches from silent mode to fail-safe mode, and the remote wake-up request is indicated by a low level at pin

RXD to interrupt the microcontroller (Figure 4-3 on page 7). EN high can be used to switch directly to normal mode.
