TMP300 Datasheet | Burr-Brown

FEATURES ACCURACY: ±1°C (typical at +25°C) PROGRAMMABLE TRIP POINT PROGRAMMABLE HYSTERESIS: 5°C/10°C OPEN-DRAIN OUTPUTS LOW-POWER: 110μA (max) WIDE VOLTAGE RANGE: +1.8V to +18V OPERATION: - 40°C to +150°C ANALOG OUT: 10m V/°C SC70-6 AND SOT23-6 PACKAGES - - - - - - - - - 2 DESCRIPTION The TMP300 is a low-power, resistor-programmable, digital output temperature switch. It allows a threshold point to be set by adding an external resistor. Two levels of hysteresis are available. The TMP300 has a VTEMP analog output that can be used as a testing point or in temperature-pensation loops. The TMP300 detects temperature with ±4°C accuracy (max) over - 40°C to +125°C. With a supply voltage as low as 1.8V and low current consumption, the TMP300 is ideal for power-sensitive systems. Available in two micropackages that have proven thermal characteristics, this part gives a plete and simple solution for users who need simple and reliable thermal management.
