EMC1001 1.5C SMBus Temperature Sensor in Miniature SOT-23 Datasheet PRODUCT FEATURES General Description Features Self Contained Internal Temperature Sensor The EMC1001 is a tiny SMBus temperature sensor with 0.25C resolution 1.5C accuracy and two interrupts. Packaged in a 1.5C Accuracy 40C to 85C SOT23-6, the EMC1001 provides an accurate, low-cost, Small 6-lead SOT lead-free RoHS compliant low-current, solution for critical temperature monitoring packages in a PC or embedded applications. SMBus address selected by external resistor Select 1 of 4 per package, 8 addresses available The EMC1001 generates two separate interrupts with programmable thermal trip points. The THERM output Maskable Interrupt using ALERT operates as a thermostat with programmable threshold One-shot Command during standby and hysteresis. The ALERT output can be configured Low Power, 3.0V to 3.6V Supply as a maskable SMBus alert with programmable 47uA at 0.0625 Conversions per Second (Typical) window comparator limits, or as a second THERM 4.8uA in Standby (Typical) output. An efficient fan control system can be created SMBus 2.0 Compliant interface since this output may be used to control a fan. Programmable temperature conversion rate A power down mode extends battery life in portable Applications applications. Desktop and Notebook Computers Each part number may be configured to respond to one Thermostats of four separate SMBus addresses.
