MAX6625, MAX6626 9位/12位温度传感器,带有I²C兼容串行接口,SOT23封装
MAX6625, MAX6626概述
The MAX6625/MAX6626 combine a
temperature sens
or, a prog
rammable overtemperature al
arm, and an I²C-compa
tible serial interf
ace into single compact packages. They convert their die temperatures into digital values using internal
analog-to-digital converte
rs (
ADCs). The result of the conversion is held in a temperature register, re
adable at any time through the serial interface. A ded
icated 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, preventing spurious alarms in noisy environments. OT has programmable 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.
