8 channel temperature sensor from Maxim

Maxim has introduced the MAX6581, a ±1°C accurate, 8-channel temperature sensor. It has seven remote sensing channels to monitor ASICs, FPGAs, CPUs, and boards with multiple hot spots. All remote channels includes series resistance cancellation and beta compensation for best accuracy. The 8-channel temperature sensor requires only one I²C address.

The MAX6581 can measure the die temperature of external ICs that have integrated thermal diodes. This temperature sensor also compensates for parasitic series resistance. All temperature channels have programmable alert and overtemperature thresholds. When the temperature of a channel exceeds the respective threshold, a status bit is set in one of the status registers. Two open-drain alarm outputs (active-low ALERT and active-low OVERT) assert corresponding to these bits in the status register(s). The 2-wire serial interface accepts SMBus protocols (write byte, read byte, send byte, and receive byte) for reading the temperature data and programming the alarm thresholds.

Package: 4mm x 4mm, 24-pin TQFN package with an exposed pad,

Operating temperature range: -40°C to +125°C.

Price: Start at US$1.24
