MAX6634MSA+

The MAX6634MSA+ is a 12bit plus sign temperature sensors with SMBus/I2C compatible serial interface in 8 pin NSOIC package. It combines temperature sensor, programmable overtemperature alarm and SMBus/I2C compatible serial interface in to a single package. The device converts its die temperature into digital values using internal ADC. The result of conversion is then held in a temperature register as a 12bit plus sign value which allows 0.0625°C resolution and can be readable at any time through serial interface. It is capable of reading temperatures up to 150°C. The MAX6634 has shutdown mode that saves power by turning off everything except power-on reset (POR) and serial interface. The MAX6634 has three address pins which allows up to eight devices to be connected to a single bus. The device incorporates dual mode active-low ALERT output (open drain) and can serve as an upgraded alternative to LM75 device. It is used in battery temperature alarms and PC temperature control.
