Hysteresis
A hysteresis value of 2癈 or 10癈 can be selected. The digital
comparator ensures excellent accuracy for the hysteresis value.
Hysteresis prevents oscillation on the output pin when the
temperature is approaching the trip point and after the output
pin is activated. For example, if the temperature trip is 45癈 and
the hysteresis selected is 10癈, the temperature must go as low
as 35癈 before the output deactivates.
TEMPERATURE CONVERSION
The conversion clock for the part is generated internally. No
external clock is required. The internal clock oscillator runs an
automatic conversion sequence. During this automatic conversion
sequence, a conversion is initiated every 600 ms. At this time, the
part powers up its analog circuitry and performs a temperature
conversion.
This temperature conversion typically takes 30 ms, after which
the analog circuitry of the part automatically shuts down. The
analog circuitry powers up again 570 ms later, when the 600 ms
timer times out and the next conversion begins. The result of
the most recent temperature conversion is compared with the
factory-set trip point value. If the temperature measured is
greater than the trip point value, the output is activated. The
output is deactivated once the temperature crosses back over
the trip point threshold, plus whatever temperature hysteresis is
selected. Figure 18 to Figure 21 show the transfer function for
the output trip pin of each generic model.
