LM66 - Dual Output Internally Preset Thermostat

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.

Features

  • 1.
  • 2 Digital Outputs Support TTL Logic Levels.
  • Internal Temperature Sensor.
  • 2 Internal Comparators with Hysteresis.
  • Internal Voltage Reference.
  • Currently Available in 8-pin SOIC Plastic Package KEY.
