Function
Enables the device in Normal Mode
System ground (optional)
Low-level watchdog trigger input from microcontroller
High-voltage input for local wake-up request; if not needed, connect directly to VS
System ground (mandatory)
System ground (optional)
LIN-bus line input/output
System ground (optional)
Receive data output
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)
Low, watchdog is on; high, watchdog is off; if not needed, connect to GND
Ignition detection (edge sensitive)
System ground (optional)
3.3V/5V regulator sense input pin
3.3V/5V regulator output/driver pin
Battery supply
Heat slug is connected to all GND pins
