Definition
1
WAKE1
Wake Input
This pin is a high-voltage input used to wake-up the LIN1 from Sleep mode.
2
TXD1
Data Input
This pin is the transmitter input of the LIN1 interface which controls the state of the bus
output.
3
LIN1
LIN Bus
This bidirectional pin represents the LIN1 single-wire bus transmitter and receiver.
4
LIN2
LIN Bus
This bidirectional pin represents the LIN2 single-wire bus transmitter and receiver.
5
INH2
Inhibit Output
This pin can have two main functions: controlling an external switchable voltage
regulator having an inhibit input, or driving an external bus resistor connected to LIN2 in
the master node application.
6
RXD2
Data Output
This pin is the receiver output of the LIN2 interface, which reports the state of the bus
voltage to the MCU interface.
7
EN2
Enable Control
This pin controls the operation mode of the LIN2 interface.
8
WAKE2
Wake Input
This pin is a high-voltage input used to wake-up the LIN2 device from Sleep mode.
9
GND
Ground
This pin is the device ground pin.
10
TXD2
Data Input
This pin is the transmitter input of the LIN2 interface, which controls the state of the bus
output.
11
VSUP
Power Supply
This pin is device battery level power supply.
12
INH1
Inhibit Output
This pin can have two main functions: controlling an external switchable voltage
regulator having an inhibit input, or driving an external bus resistor connected to LIN1 in
the master node application.
13
RXD1
Data Output
This pin is the receiver output of the LIN1 interface, which reports the state of the bus
voltage to the MCU interface.
14
