Update: 28 September, 2023
The MAX6625/MAX6626 combine a temperature sensor, a programmable overtemperature alarm, and an I2C- 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 I2C-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, or the 6-pin TDFN package.
