To prevent output "chattering" when measured tem-
perature is at (or near) the programmed trip point values, the
LOW SET and HIGH SET inputs each have a built-in
hysteresis of – 2
°
C max. As a result, the HIGH LIMIT and
LOW LIMIT outputs remain active until the measured tem-
perature falls a maximum of 2
°
C below the programmed
HIGH SET and LOW SET thresholds as shown in Figure 3.
The programmed setting threshold of Figure 3 is user-
programmed temperature trip points of either the LOW SET
or HIGH SET inputs. The LOW LIMIT or HIGH LIMIT output
is driven active when temperature equals the programmed
setpoint value (to within 3
°
C). The output remains active
until the temperature falls an additional 2
°
C below the
setpoint due to hysteresis.
APPLICATIONS
Mounting
If the TC623 is used to measure the temperature
of another device, it is important that the top surface
of the TC623 package be in intimate contact with the
measured device. Good thermal conductivity and no air
space is critical to accurate temperature measurement in
applications of this type.
Trip Point Programming
The resistance values required for the HIGH SET and
LOW SET inputs are calculated using the formula below:
R
TRIP
= 0.5997 x T
2.1312
Where Rtrip = Programming resistor value in Ohms
T = Desired trip temperature in degrees Kelvin.
For example, to program a trip point of 50
°
C, the
programming resistor is:
R
TRIP
= 0.5997 x (50 + 273.15)
2.1312
) = 133,652
