The GND-Off Comparator is used to detect a voltage difference between the GND pin
and TST1 (which must be soldered to GND in the application). It activates the
bit. This circuit can detect a disconnection of the Supply GND Pin.

case, the TLE5011 is supplied by the SCK, CLK and CS input pins via the ESD
structures. It activates the
The retriggerable analog monoflop is necessary because of the non-static signal of the
CLK and SCK signals.
This comparator is also activated if spikes on CLK or SCK achieve the condition:
