The internal oscillator is trimmed to a tolerance of < ±10%. This means that t 1 and t 2 can also vary by ±10%. The following cal-
culation shows the worst case calculation of the watchdog period T wd which the microcontroller has to provide.
t 1min = 0.90 × t 1 = 10.87ms, t 1max = 1.10 × t 1 = 13.28ms
t 2min = 0.90 × t 2 = 8.65ms, t 2max = 1.10 × t 2 = 10.57ms
T wdmax = t 1min + t 2min = 10.87ms + 8.65ms = 19.52ms
T wdmin = t 1max = 13.28ms
T wd = 16.42ms ±3.15ms (±19.1%)
Figure 3-4 above shows the typical watchdog period T WD depending on the value of the external resistor R OSC .
A reset will be active for V CC < V tHRESx ; the level V tHRESx is realized with a hysteresis (HYS RESth ).

LIN Transceiver
A bi-directional bus interface is implemented for data transfer between the LIN bus and the local LIN protocol controller.
The transceiver consists of a low side driver (1.2V at 40mA) with slew rate control, wave shaping, current limitation, and a
high-voltage comparator followed by a debouncing unit in the receiver.
Transmit Mode
During transmission, the data at the pin TX will be transferred to the bus driver to generate a bus signal on pin LIN.
To minimize the electromagnetic emission of the bus line, the bus driver has an integrated slew rate control and wave-shaping
unit. Transmission will be interrupted in the following cases:
●
●
Thermal shutdown active or overtemperature LIN active
Sleep mode
