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°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.
