The MAX6625/MAX6626 combine a temperature sensor,
a programmable overtemperature alarm, and an I
compatible serial interface into single compact packages.
They convert their die temperatures into digital values
using internal analog-to-digital converters (ADCs). The
result of the conversion is held in a temperature register,
readable at any time through the serial interface. A dedi-
cated alarm output, OT, activates if the conversion result
exceeds the value programmed in the high-temperature
register. A programmable fault queue sets the number of
faults that must occur before the alarm activates, prevent-
ing spurious alarms in noisy environments. OT has pro-
grammable output polarity and operating modes.
The MAX6625/MAX6626 feature a shutdown mode that
saves power by turning off everything but the power-on
reset and the I
addresses can be configured with the ADD pin, allowing
up to four MAX6625/MAX6626 devices to be placed on
the same bus. The MAX6625P/MAX6626P OT outputs are
open drain, and the MAX6625R/MAX6626R OT outputs
include internal pullup resistors.
The MAX6625 has a 9-bit internal ADC and can function
as a replacement for the LM75 in most applications. The
MAX6626 has a 12-bit internal ADC. Both devices come
in the space-saving 6-pin SOT23 package, or the 6-pin
TDFN package.
