GND

LIN

Low-level watchdog trigger input from microcontroller

High-voltage input for local wake-up request; if not needed, connect to VS

System ground (mandatory)

System ground (optional)

LIN-bus line input/output

GND

RXD

System ground (optional)

Receive data output

INH

Battery related output for controlling an external voltage regulator

Transmit data input; active low output (strong pull down) after a local wake-up request

Output undervoltage and watchdog reset (open drain)

External resistor for adjustable watchdog timing

For factory testing only (tie to ground)

For debug mode: low, watchdog is on; high, watchdog is off
