Abstract: A LIN receiver includes a single, low power structure for both sleep and silent modes, with a single comparator for detecting LIN signaling during both sleep and silent modes as well as during active mode. In some embodiments, full receiving capability is implemented with a current as low as 5 microamps. In particular, dominant and recessive levels for the wakeup bloc are identical to those of standard LIN levels, fixed at about 3.5 V. Consequently, full LIN receiving capability is available during sleep mode.

Abstract: A double-diffused metal oxide semiconductor (DMOS) structure is configured as an open drain output driver having electrostatic discharge (ESD) protection and a reverse voltage blocking diode inherent in the structure and without requiring metal connections for the ESD and reverse voltage blocking diode protections.

Abstract: Mutual triggering of electrostatic discharge (ESD) fingers is improved by creating a base contact in each individual finger and connecting all of these base contacts in parallel. The local base contact in each ESD finger is located at a position where the base voltage significantly increases when the ESD current increases. Thus when an ESD finger is triggered its local base voltage will tend to significantly increase. Since all of the ESD finger bases are connected in parallel this local voltage increase will forward bias the base-emitter junctions of the other ESD fingers, thus triggering them all. By sharing the triggering current from the fastest ESD finger with the slower ones ensures that all ESD fingers are triggered during an ESD event.
