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.
