boundary has been met or exceeded, or as part of a closed loop system it can be used to activate a heating
system and deactivate it when the system temperature returns to tolerance.
The T
COM
output goes high when the measured temperature meets or exceeds TH, and will stay high until
the temperature equals or falls below TL. In this way, any amount of hysteresis can be obtained.

OPERATION AND CONTROL
The DS1620 must have temperature settings resident in the TH and TL registers for thermostatic
operation. A configuration/status register also determines the method of operation that the DS1620 will
use in a particular application and indicates the status of the temperature conversion operation. The
configuration register is defined as follows:

DONE = Conversion Done Bit. 1=conversion complete, 0=conversion in progress.

the device. This feature provides a method of determining if the DS1620 has ever been subjected to
temperatures above TH while power has been applied.
