This 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
This circuit can detect a disconnection of the Supply GND Pin.

This comparator detects a disconnection of the V
TLE5010 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 not static signal of the
CLK and SCK signals.
This comparator is also activated, if spikes on CLK or SCK achieve the condition:
