Comparator/Interrupt Modes
INT/CMPTR behaves differently depending on whether
the TCN75 is in Comparator mode or Interrupt mode.
Comparator mode is designed for simple thermostatic
operation. INT/CMPTR will go active anytime TEMP
exceeds T
. When in Comparator mode, INT/
SET
CMPTR will remain active until TEMP falls below
T
, whereupon it will reset to its inactive state. The
HYST
state of INT/CMPTR is maintained in Shutdown mode
when the TCN75 is in Comparator mode. In Interrupt
mode, INT/CMPTR will remain active indefinitely, even
if TEMP falls below T
, until any register is read via
HYST
the 2-wire bus. Interrupt mode is better suited to inter-
rupt driven microprocessor-based systems. The INT/
CMPTR output may be wire-OR’ed with other interrupt
sources in such systems. Note that a pull-up resistor is
necessary on this pin since it is an open-drain output.
Entering Shutdown mode will unconditionally reset INT/
CMPTR when in Interrupt mode.
