LM66 Datasheet (National Semiconductor) - Dual Output Internally Preset Thermostat

LM66, Dual Output Internally Preset Thermostat

The LM66 is a precision low power thermostat.

Two stable temperature trip points (VT1 and VT2) are generated by dividing down the LM66 1.250V bandgap voltage reference using a resistors divider network.

The LM66 has two digital outputs.

OUT1 goes LOW when the temperature exceeds T1 and goes HIGH whe
