Description

ZMD30011 is a CMOS integrated circuit for

application in a Local Interconnect Network (LIN).

The device is used as a part of a master or slave

node and works as an interface between the

physical bus and the protocol controller.

It realizes data switching (between bus and

TXD/RXD) and level shifting (between battery

voltage and controller voltage).

ZMD30011 is equipped with sleep mode and wake-

up-function to reduce power consumption. It has a

battery related output to control an external voltage

regulator which supplies other devices.

The IC is optimised for automotive environments by

it’s very low standby current, excellent

electromagnetic compatibility, ESD protection and

thermal overload protection.
