Digital temperature sensor with overtemperature alarms
7.9.2 T_CRIT
output
The T_CRIT
output is LOW when any temperature reading is greater than the preset limit
in the corresponding critical temperature setpoint register. When one of the T_CRIT
setpoint temperatures is exceeded, the appropriate status register bit, 1 (RCRIT) or 0
(LCRIT), is set.
After every local and remote temperature conversion the status register flags and the
T_CRIT
output are updated. Figure 7
is a timing diagram showing the relationship of
T_CRIT
output, Status bit 1 (RCRIT) and the remote critical temperature setpoint (RCS),
and critical temperature hysteresis (TH) with remote temperature changes. Note that the
T_CRIT
output is de-activated only after the remote temperature is below the remote
temperature setpoint, RCS minus the hysteresis, TH. In the interrupt mode only, the
Status register flags are reset after the Status register is read.
Event A: T_CRIT
goes LOW and Status bit 1 (RCRIT) is set HIGH when Remote
Temperature exceeds RCS, Remote T_CRIT Setpoint.
Event B: Remote Temperature goes below RCS - TH. T_CRIT
is de-activated, but
Status register remains unchanged.
