TMP708 is a resistor programmable temperature switch with 10°C and 30°C hysteresis
Product Details
describe:
The TMP708 is a fully integrated AO4304 resistance programmable temperature switch with a temperature threshold set by only one external resistor over the entire operating range. The TMP708 provides an open-drain, active-low output with a supply voltage range of 2.7V to 5.5V.
Temperature threshold accuracy is typically ±0.5°C, with a maximum of ±3°C (60°C to 100°C). Quiescent current consumption is typically 40 μA. Hysteresis is pin selectable to 10°C or 30°C.
The TMP708 is available in a 5-pin SOT-23 package.
