LIN Transceiver with 3.3V Voltage Regulator
Data Sheet
7.0
Functional Description
7.1 Overall Functional Description
LIN is a serial communication protocol that efficiently supports the control of mechatronic nodes in distributed automotive applications.
The domain is class-A multiplex buses with a single master node and a set of slave nodes.
AMIS-40615 is designed as a master or slave node for the LIN communication interface with integrated 3.3V voltage regulator having a
current capability up to 50mA for supplying any external components (microcontroller).
AMIS-40615 contains the LIN transmitter, LIN receiver, voltage regulator, power-on-reset (POR) circuits, and thermal shutdown (TSD).
The LIN transmitter is optimized for the maximum specified transmission speed of 20kBaud with EMC performance due to reduced slew
rate of the LIN output.
The junction temperature is monitored via a thermal shutdown circuit that switches the LIN transmitter and voltage regulator off when
temperature exceeds the TSD trigger level.
AMIS-40615 has four operating states (normal mode, low slope mode, stand-by mode, and sleep mode) that are determined by the
input signals EN, WAKE, STB, and TxD.
7.2 Operating States
AMIS-40615 provides four operating states, two modes for normal operation with communication, one stand-by without communication
and one low power mode with very low current consumption. See Figure 4.
