•

ACCURACY: ±1°C (typical at +25°C)

The TMP300 is a low-power, resistor-programmable,

digital output temperature switch. It allows a threshold

•

PROGRAMMABLE TRIP POINT

point to be set by adding an external resistor. Two

•

PROGRAMMABLE HYSTERESIS: 5°C/10°C

levels of hysteresis are available. The TMP300 has a

•

OPEN-DRAIN OUTPUTS

•

LOW-POWER: 110mA (max)

point or in temperature-compensation loops.

•

WIDE VOLTAGE RANGE: +1.8V to +18V

With a supply voltage as low as 1.8V and low current

consumption, the TMP300 is ideal for power-sensitive

•

OPERATION: –40°C to +150°C

systems.

•

ANALOG OUT: 10mV/°C

Available in two micropackages that have proven
