Function

Battery supply for the voltage divider

Enables the device into Normal Mode

Low-level watchdog trigger input from microcontroller; if not needed, connect to PVCC

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

System ground

LIN-bus line input/output

Receive data output

Input to switch on the internal voltage divider, active high; if not needed, connect to GND

Voltage divider output

Input to switch the transceiver in High-speed Mode, active high

Battery related High-side switch

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; if not needed, connect to GND

For factory testing only (tie to ground)

Low watchdog is on; high watchdog is off

Ignition detection (edge sensitive); if not needed, connect to GND

3.3V/5V regulator sense input pin, connect to VCC

3.3V/5V regulator output/driver pin, connect to PVCC

Battery supply

Heat slug is connected to GND
