Active: In Production.

Description

The 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 is stored in a temperature register as a 13-bit word, which allows 0.0625° resolution. The temperature data is readable at any time through the serial interface. The operating temperature range is -55° to +150°.

The MAX6662 provides two programmable watchdog interrupt outputs. Active-Low ALERT is used for lower temperature warning functions, while active-low 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.
