LM56
Dual Output Low Power Thermostat
General Description
The LM56 is a precision low power thermostat. Two stable
temperature trip points (V
and V
T1
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
). Similarly, OUT2 goes LOW when the tempera-
HYST
ture exceeds T2 and goes HIGH when the temperature goes
below (T2–T
). T
is an internally set 5˚C typical

hysteresis.
The LM56 is available in an 8-lead Mini-SO8 surface mount
package and an 8-lead small outline package.
