Both modes have the Window watchdog feature, and the SPI mode has an additional Timeout watchdog feature. On the TLINx441x, the window is a 50%/50% split of the configured timer in both PIN and SPI mode; that is, whatever time length is configured, 50% of that value will be open...
Both these tasks must be completed before tCONFIG expires. A window watchdog fault occurs if the time between rising clock edges is either too short (a "fast" fault) or too long (a "slow" fault). The "fast" and "slow" limits, tWD(FAST) and tWD(SLOW), are selected with WWD_TIMER...
Only Autonomous can do a trigger based on a Wake event. In Normal mode, Autonomous works like a time-out (always enabled). When using the window watchdog it is important to understand the closed and open window aspects. The device is set up with a 50%/50% open and closed window and...
The A4412 contains a Window Watchdog timer with a detect period of 2 ms. The watchdog timer is activated once it receives valid 2 ms pulses from the processor. The watchdog can be put into flash mode or be reset via secure SPI commands. Protection features include undervoltage and ...

The watchdog defaults to a window watchdog for both control methods but for flexibility the device can be configured as a window or timeout watchdog with greater than 20 different time windows when SPI control is used. The LIN transceiver provides a 200 kbps fast mode for end of line ...
Voltage scaling is done using a resistor ladder, but for differential mode channels, a chopping circuit is used to get the average of both of the voltages (VMON + VMON_RS)/2 since VMON_RS can be negative and can't be converted into an ADC code. VMON – VMON_RS is calculated ...
