General Description

The MAX6625/MAX6626 combine a temperature sensor,

a programmable overtemperature alarm, and an I

C™-

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

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

C-compatible interface. Four separate

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.
