LM95221 Dual Remote Diode Digital Temperature Sensor with SMBus Interface
Checkfor Samples: LM95221
1FEATURES APPLICATIONS Accurately Senses Die Temperatureof Remote • Processor/Computer System Thermal
ICsor Diode Junctions Management (e.g. Laptop, Desktop,
Workstations, Server)• Remote Diode Fault Detection Electronic Test Equipment• On-board Local Temperature Sensing Office Electronics• Remote Temperature Readings 0.125°C LSb DESCRIPTION– 10-bits Plus Signor 11-bits Programmable
The LM95221isa dual remote diode temperatureResolution sensorin an 8-lead VSSOP package. The 2-wire 11-bits Resolves Temperatures Above serial interfaceof the LM95221is compatible with
127°C
SMBus 2.0. The LM95221 can sense three
temperature zones,it can measure the temperature• Local Temperature Readings of its own die as well as two diode connected– 0.25°C transistors. The diode connected transistors can bea 9-bits Plus Sign thermal diode as found in Pentium and AMD
processors or can simply bea diode connected• Status Register Support MMBT3904 transistor. The LM95221 resolution• Programmable Conversion Rate Allows User format for remote temperature readings can beOptimizationof Power Consumption programmed to be 10-bits plus sign or 11-bits Shutdown Mode One-shot Conversion Control unsigned.In the unsigned mode the LM95221 remote
diode readings can resolve temperatures above• SMBus 2.0 Compatible Interface, Supports 127°C. Local temperature readings havea resolutionTIMEOUT of 9-bits plus sign.• 8-pin VSSOP Package
The temperature of any ASIC can be accurately
determined using the LM95221 as long as aKEY SPECIFICATIONS dedicated diode (semiconductor junction)is available• Local Temperature Accuracy on the target die. The LM95221 remote sensor TA= 0°Cto 85°C± 3.0°C (max) accuracyof ±1°Cis factory trimmed fora series
resistanceof 2.7 ohms and 1.008 non-ideality factor.• Remote Diode Temperature Accuracy TD= 45°Cto 85°C TDto 140°C
