3.13 TM Input Pin

3.14 KL_15 Pin

The TM pin is used for final production measurements at Atmel^®. In normal application, it has to

be always connected to GND.

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 is at high

voltage (V_Batt), it is possible to switch the IC into Sleep or Silent Mode. Connect the KL_15 pin

directly to GND if you do not need it. A debounce timer with a typical Tdb_{Kl_15}of 160 µs is

implemented.

The input voltage threshold can be adjusted by varying the external resistor due to the input cur-

rent I_{KL_15}. To protect this pin against voltage transients, a serial resistor of 47 kΩ and a ceramic

capacitor of 100 nF are recommended. With this RC combination you can increase the wake-up

time Tw_{KL_15}and, therefore, the sensitivity against transients on the ignition Kl.15.

You can also increase the wake-up time using external capacitors with higher values.

3.15 INH Output Pin

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

1 kΩ master resistor via the INH pin for master node applications. The INH pin is switched off

during VCC undervoltage reset.

3.16 Reset Output Pin (NRES)

The Reset Output pin, an open drain output, switches to low during V_CCundervoltage or a

watchdog failure.

3.17 WD_OSC Output Pin

The WD_OSC Output pin provides a typical voltage of 1.2V, which supplies an external resistor

with values between 34 kΩ and 120 kΩ to adjust the watchdog oscillator time.

3.18 NTRIG Input Pin

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

minimum time t_trigminto generate a watchdog trigger.

3.19 Wake-up Events from Sleep or Silent Mode

• LIN-bus

• WAKE pin

• EN pin

• KL_15
