Note 1: Limits are 100% production tested at TA = +25NC. Limits over the operating temperature range are guaranteed by design.
Note 2: NC includes external NTC thermistor error. % of THMSW excludes thermistor beta error and external pullup error. NTC
thermistor assumed to be 10kI nominal, part number Vishay NTHS0603N02N1002FF, external pullup resistor = 10kI.
