LM56
Dual Output Low Power Thermostat
General Description
The LM56 is a precision low power thermostat. Two stable
temperature trip points (V
T1
and V
T2
) are generated by divid-
ing 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 temperature exceeds
T2 and goes HIGH when the temperature goes below
(T2–T
HYST
). T
HYST
is an internally set 5C typical hysteresis.
The LM56 is available in an 8-lead Mini-SO8 surface mount
package and an 8-lead small outline package.
