LM56

Dual Output Low Power Thermostat

General Description

The LM56 is a precision low power thermostat. Two stable

temperature trip points (V

dividing down the LM56 1.250V bandgap voltage reference

using 3 external resistors. The LM56 has two digital outputs.

OUT1 goes LOW when the temperature exceeds T1 and

goes HIGH when the the temperature goes below

(T1–T

ture exceeds T2 and goes HIGH when the temperature goes

below (T2–T

hysteresis.

The LM56 is available in an 8-lead Mini-SO8 surface mount

package and an 8-lead small outline package.
