THERMOSTAT OPERATION
The DS600 can also be used as a thermostat with either an active-high (TO) or active-low ( TO) output. To function
as a thermostat, a precise voltage reference equal to the desired threshold must be applied to the V
TH
pin. When
the temperature with the equivalent voltage value is reached (voltage on V
OUT
= voltage on V
TH
), thermostat outputs
TO and TO become active. Figure 3 shows an example thermostat application circuit.
