EVENT-Output Functionality
The EVENT output indicates conditions such as the
temperature crossing a predefined boundary. It oper-
ates in one of the three modes: interrupt mode, com-
parator mode, and critical-temperature-only mode.
Figure 3 shows an example of the measured tempera-
ture vs. time, with the corresponding behavior of the
EVENT output in each of these modes. See the EVENT
Operation Modes section for descriptions of the two
modes. The EVENT modes are selected using the con-
figuration register.
Event-output polarity can be set to active high or active
low through the configuration register (bit 1). The
EVENT output can also be disabled so that EVENT is
always high impedance (bit 3). Upon device power-up,
the default condition for the EVENT output is high
impedance. Writing a 1 to bit 3 of the configuration reg-
ister enables the EVENT output.
EVENT Thresholds
Alarm Window Trip
The MAX6604 provides a comparison window with an
upper-temperature trip point and a lower-temperature
trip point, programmed through the alarm-upper-
boundary register and the alarm-lower-boundary regis-
ter, respectively. When enabled, the EVENT output
triggers whenever entering or exiting (crossing above
or below) the alarm window (Figure 3).
Critical Trip
The critical temperature setting is programmed in the
critical temperature register. When the temperature
reaches the critical temperature value in this register
(and EVENT is enabled), the EVENT output asserts and
cannot be deasserted until the temperature drops
below the critical temperature threshold.
EVENT Operation Modes
Comparator Mode
In comparator mode, the EVENT output behaves like a
window-comparator output that asserts when the tem-
perature is outside the window. Reads/writes on the
MAX6604s registers do not affect the EVENT output in
comparator mode. The EVENT signal remains asserted
until the temperature goes inside the alarm window or
the window thresholds are reprogrammed so that the
current temperature is within the alarm window.
Interrupt Mode
In interrupt mode, EVENT asserts whenever the temper-
ature crosses an alarm window threshold. After such an
event occurs, writing a 1 to the clear event bit in the con-
figuration register deasserts the EVENT output until the
next trigger condition occurs. The trip threshold value in
