Atmel ATA6623/ATA6625
This is the normal transmitting and receiving Mode of the LIN Interface, in accordance with LIN
specification 2.x. The V
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.
A falling edge at EN while TXD is high switches the IC into Silent Mode. The TXD Signal has

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.
