First Temperature Sensor with Dual SMBus Interface to Allow Two Controllers Simultaneous Access to Temperature Data
SUNNYVALE, CA—September 5, 2006—Maxim Integrated Products (NASDAQ: MXIM) introduces the MAX6638, a ±1.0°C accurate thermal sensor with two independent SMBus™ serial ports. The dual SMBus interface lets a GPU card controller and a CPU board controller access the temperature data of the GPU chip and graphics card, thereby eliminating communication errors. The MAX6638 also monitors its own internal temperature. The combination of high accuracy and multiple temperature monitoring makes the MAX6638 ideal for next-generation notebook computers with upgradeable graphics systems.
The MAX6638's high ±1.0°C temperature accuracy enhances overall system performance. The device also offers one programmable OT (overtemperature) output and two programmable ALERT outputs, further improving overall system reliability.
Packaged in a 16-pin TQFN, the MAX6638 operates over the 3.0V to 5.5V supply-voltage range while consuming only 500µA of supply current. This device is specified over the -40°C to +125°C temperature range. Prices start at $1.75 (1000-up, FOB USA).
