Table 2-1. Pin Description

Pin Symbol Function

1 VBATT Battery supply for the voltage divider

2 EN Enables the device into Normal Mode

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

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

5 GND System ground

6 LIN LIN-bus line input/output

7 RXD Receive data output

8 DIV_ON Input to switch on the internal voltage divider, active high

9 PV Voltage divider output

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

11 INH Battery related High-side switch

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

13 NRES Output undervoltage and watchdog reset (open drain)

14 WD_OSC External resistor for adjustable watchdog timing; if not needed, connect to GND

15 TM For factory testing only (tie to ground)

16 MODE For Debug Mode: Low watchdog is on; high watchdog is off

17 KL_15 Ignition detection (edge sensitive)

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

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

20 VS Battery supply

Backside Heat slug is connected to GND
