Symbol
Function
1
RXD
Receive data output (open drain)
2
EN
Enables normal mode; when the input is open or low, the device is in sleep mode
3
WAKE
High voltage input for local wake-up request. If not needed, connect directly to VS
4
TXD
Transmit data input; active low output (strong pull-down) after a local wake-up request
5
GND
Ground, heat sink
6
LIN
LIN bus line input/output
7
VS
Battery supply
8
INH
Battery-related inhibit output for controlling an external voltage regulator or to switch-off the LIN master
pull-up resistor; active high after a wake-up request
