Temperature sensor monitors ASICs, FPGAs and CPUs

The MAX6581, a +/-1C accurate, eight-channel temperature sensor, has seven remote sensing channels to monitor ASICs, FPGAs, CPUs and boards with multiple hot spots.
Each remote channel includes series resistance cancellation and beta compensation  for best accuracy.


Because the MAX6581 contains eight channels of temperature sensing, but requires only a single I2C address for these eight channels, it reduces board area and overall system cost.



This part replaces up to eight local sensors or seven single-channel remote sensors and can measure the die temperature of external ICs that have integrated thermal diodes.
The MAX6581 also compensates for parasitic series resistance.
Additionally, any of the seven remote channels can be used to measure board temperature using a discrete diode-connected transistor.
Offered in a 4 x 4mm, 24-pin TQFN package with an exposed pad, the MAX6581 is specified for an operating temperature range of -40 to 125C.
