ISO5451-Q1: DESAT glitch filter delay

Part Number: ISO5451-Q1

Team, I have a question about ISO5451-Q1's DESAT glitch filter delay.

In the datasheet Figure 40, the DESAT glitch filter delay is not marked. So I want to confirm if it is before the tDESAT (10%) or contained in the tDESAT (10%). Or you will have other explanation.

    Hi,

    The DESAT deglitch filter delay, t_DESAT(GF), is not marked on this diagram. t_DESAT (10%) is the typical delay from the moment the voltage at DESAT goes above the threshold to the moment the output voltage is 10% higher than the output low voltage. The deglitch filter delay is part of that 10% delay. The deglitch filter time delay is typically 330ns and the DESAT delay is typically 415ns.

    Hope this helps,

    Nancy
