TYPICAL APPLICATIONS

4.1

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.

4.2

Trip Point Programming

The resistance values required for the HIGH SET and

LOW SET inputs are calculated using the formula

below:

For example, to program a trip point of 50°C, the

programming resistor is:

RTRIP = 0.5997 x T

2.1312

Where;

RTRIP = Programming resistor value in Ohms

T = Desired trip temperature in degrees Kelvin.

RTRIP = 0.5997 x (50 + 273.15)

2.1312) = 133.65 k
