Note 1: Limits are 100% production tested at T A = +25 N C. Limits over the operating temperature range are guaranteed by design.
Note 2: N C includes external NTC thermistor error. % of THMSW excludes thermistor beta error and external pullup error. NTC
thermistor assumed to be 100k I Q 1% nominal, part number Vishay NTHS0603N01N1003FF, external pullup resistor =
100k I Q 1%.
