... NEGATIVE-GOING V TRANSIENTS CC To avoid unnecessary resets caused by fast power supply transients, the ADM823/ADM824/ADM825 are equipped with glitch rejection circuitry. The typical performance characteristic in Figure 12 plots V transient duration vs. the transient mag- CC nitude. The curves show combinations of transient magnitude and duration for which a reset is not generated for 4 ...
