Wake-up Events from Sleep or Silent Mode
The KL_15 pin is a high-voltage input used to wake up the device from Sleep or Silent Mode.
It is an edge sensitive pin (low-to-high transition). It is usually connected to ignition to generate
a local wake-up in the application when the ignition is switched on. Although KL_15 pin isat

160µs is implemented.
The input voltage threshold can be adjusted by varying the external resistor due to the input

ceramic capacitor of 100nF are recommended. With this RC combination you can increase the
wake-up time Tw
You can also increase the wake-up time using external capacitors with higher values.
The INH Output pin is used to switch an external voltage regulator on during Normal or
Fail-safe Mode. The INH pin is switched off in Sleep or Silent Mode. It is possible to switch off
the external 1k master resistor via the INH pin for master node applications. The INH pin is
switched off during VCC undervoltage reset.
The Reset Output pin, an open drain output, switches to low during V
watchdog failure.
The WD_OSC Output pin provides a typical voltage of 1.2V, which supplies an external resis-
tor with values between 34k and 120k to adjust the watchdog oscillator time.
The NTRIG Input pin is the trigger input for the window watchdog. A pull-up resistor is imple-
mented. A negative edge triggers the watchdog. The trigger signal (low) must exceed a
