It allows a temperature threshold point to be set by adding an externalresistor. Two levels of hysteresis are available. TMP300 also has an analog output (V TEMP ) thatcan be used as a testing point or in temperature compensation loops. With a supply voltage aslow as 1.8V, low current consumption <strong>and</strong> a tiny SC70 package, the TMP300 is ideal forpower- <strong>and</strong> space-sensitive applications.V TEMPT SETR SETTMP300TempSensor220kΩV+R PULL- UPOVERTEMPHYST SETTMP300 functional block diagram. *Expected release date 4Q 2007Temperature SwitchTrip Point Specified Temp Operating Temp I QAccuracy Output Range Range Supply Voltage (µA)Device Description (˚C) (typ) (mV/˚C) (˚C) (˚C) (V) (max) Package(s) Price *TMP300 Comparator-Output Temperature ±1 10 –40 to +125 –40 to +150 1.8 to 18 90 SC-70 $0.70Switch w/Additional Analog Output* Suggested resale price in U.S. dollars in quantities of 1,000.
