EMCT03
1°C Triple SMBus
Temperature Sensor
Datasheet
www.DataSheet4U.com
General Description
The EMCT03 is a System Management Bus (SMBus)
temperature sensor that is capable of monitoring three
temperature zones. The three temperature zones
consist of two external and one internal temperature
diode. The internal 11 bit sigma-delta ADC architecture
with digital filtering attributes to superb linearity and
immunity to interference and noise. An extended
temperature format may be selected for compatibility
with a broad range of CPUs. Selectable conversion
rates and standby mode support low-power operation.
Features
■ Low Power; 3.0V to 3.6V Supply
— Programmable conversion rate
— < 1mA at 16 Conversions per Second
— < 3uA in Standby Mode
■ SMBus 2.0 Compliant interface
■ Two External Temperature Monitors:
— Range -64°C to +191°C
— 0.125°C resolution
— ±1°C Accuracy 40°C to 80°C
— Diode Fault Reporting
■ Internal Temperature Monitor
— Range 0°C to +85°C
— 0.125°C resolution
— ±3°C Accuracy 0°C to 85°C
■ Programmable Conversion Rate
■ MSOP-8 3x3mm Package; Green, Lead-Free
Package also available.
