... RP 0V Figure 17. Reset Timing Diagram OPEN-DRAIN RESET OUTPUT The ADM6320/ADM6321/ADM6322 have an active-low, open- drain reset output. This output structure requires an external pull-up resistor to connect the reset output to a voltage rail no higher than 6 V. The resistor should comply with the micro- processor’s logic low and logic high voltage level requirements while supplying input current and leakage paths on the RESET line kΩ ...

... TRANSIENTS CC To avoid unnecessary resets caused by fast power supply transients, the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ ADM6321/ADM6322 are equipped with glitch rejection circuitry. The typical performance characteristic in Figure 14 plots V transient duration vs. the transient magnitude. The curves show combinations of transient magnitude and duration for which a reset is not generated for 4.63 V and 2.93 V reset threshold parts. For example, with the 2.93 V threshold, a transient that goes 100 mV below the threshold and lasts 8 μ ...
