Temperature monitors boast high accuracy
Keywords:temperature sensors? thermal diodes?
The MAX6622/MAX6636 increase flexibility by allowing the user to program the temperature threshold of alarm outputs. These outputs can serve as interrupts, they can be connected to a system fan, or they can be used for other thermal-management circuitry, further enhancing flexibility. Additionally, these devices offer a hardware-standby function that eliminates false alerts at system boot.
The MAX6622/MAX6636 communicate through a two-wire SMBus-compatible interface. They operate from a 3V to 5.5V supply voltage range, and they consume only 500?A of supply current and 30?A in standby mode. Packaged in small 16-/20-pin TSSOP packages, these devices are fully specified over the -40C to 125C temperature range. Prices start at $3 for the MAX6622 and $3.75 for the MAX6636 (1,000-up).
