MAX6652
Writing a 1 to bit 0 of the configuration register starts
the monitoring function. The device will perform a
sequential sampling of all the inputs, starting with the
internal temperature sensor and continuing with 2.5VIN,
12VIN, 3.3VIN, and VCC. If the master terminates the
conversion, the sequential sampling will not stop until
the sampling cycle is completed and the results are
stored. When it starts again, it will always start with the
temperature measurement.
An interrupt signal is generated when a temperature
measurement goes above the hot limit or when a volt-
age measurement is either above the high limit or
below the low limit. This will cause the open-drain out-
put (ALERT) to go to the active-low state and set each
corresponding interrupt status bit (bits 0 through 4) to 1
(Table 5). The interrupt will be cleared by reading the
interrupt status register, except for temperature inter-
rupts generated in comparator mode. Reading the
interrupt status register also clears the register itself,
except for temperature interrupt bits set in comparator
mode.
Unless the fault is removed, the ALERT output will only
remain cleared until the end of the next conversion
cycle where it will again be asserted. The ALERT output
can also be masked by writing to the appropriate bits in
the interrupt mask register (Table 6) or by setting bit 1
of the configuration register (Table 4) to 0.
ADC and Multiplexer
The ADC integrates over a 66ms period, an integral
multiple of the line period with excellent noise rejection.
The internal oscillator is trimmed to produce a 66ms
conversion time for temperature and 33ms for each
voltage. This is equivalent to 4 and 2 cycles of 60Hz,
respectively, and provides protection against noise
pickup from the main supply. The internal oscillation
frequency can be changed to provide the same protec-
tion against 50Hz by setting bit 7 in the configuration
register to 1 (Table 4). The multiplexer automatically
sequences through the inputs, measuring voltages, and
temperature.
