Note 1: The MAX6662 is not recommended to operate above +125°C for an extended period of time
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
DescriptionThe MAX6662 is a 12-bit + sign temperature sensor combined with a programmable overtemperature alarm and a 3-wire (SPI™-compatible) serial interface in a single package. It converts its die temperature into digital values using an internal analog-to-digital converter (ADC). The temperature data of MAX6662 is stored in a temperature register as a 13-bit word, which allows 0.0625°C resolution.The temperature data is readable at any time through the serial interface. The operating temperature range is -55°C to +150°C.
The MAX6662 provides two programmable watchdog interrupt outputs. ALERT is used for lower temperature warning functions, while OT is used for higher temperature-critical functions, such as power-supply shutdown.The MAX6662 features a shutdown mode that saves power by disabling everything except the serial interface.The temperature sensor is available in an 8-pin SO package.
