How should I select a pull-up resistor for a voltage detector?
Voltage Detectors (Reset ICs)How to use
VDS-IOUT characteristics of the NMOS driver is described in Typical Characteristics on datasheets. VDS value refers to the output voltage at low level. First, find the IOUT at desired VDS from the figure. Second, calculate pull-up resistance by the formula below:
[(Pull-up voltage) - (Output voltage at low level)] / IOUT
Then, determine the pull-up resistance value (much) higher than the result of the calculation.
