General Description
LM66 General Description
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 when the the temperature goes below (T1THYST). Similarly, OUT2 goes LOW when the temperature exceeds T2 and goes HIGH when the emperature goes below (T2THYST). THYST is an internally set 5°C typical hysteresis.
The LM66 is currently available in an 8-lead small outline package.
