MAX6625RMTT+T

MAX6625RMTT+T is a temperature sensor. It features programmable overtemperature alarm, and an I²C-compatible serial interface into single compact packages. It converts their die temperatures into digital values using internal analogue-to-digital converters (ADCs). The result of the conversion is held in a temperature register, readable at any time through the serial interface. A dedicated 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. It features a shutdown mode that saves power by turning off everything but the power-on reset and the I²C-compatible interface. It is used in applications such as fan control, temperature alarms, system temperature control, industrial equipment.
