EMC1001 1.5C SMBus Temperature Sensor in Miniature TSOT Features General Description Self-Contained Internal Temperature Sensor The EMC1001 is a tiny SMBus temperature sensor with 1.5C accuracy and two interrupts. Packaged in - +0.25C resolution a SOT23-6, the EMC1001 provides an accurate, - 1.5C Accuracy +40C to +85C low-cost, low-current solution for critical temperature SMBus Address Selected by External Resistor: monitoring in a PC or in embedded applications. - Select 1 of 4 per package, 8 addresses The EMC1001 generates two separate interrupts with available programmable thermal trip points. The THERM output Maskable Interrupt using ALERT pin 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 win- dow comparator limits, or as a second THERM output. 47 A at 0.0625 Conversions per Second (Typical) An efficient fan control system can be created since this output may be used to control a fan. 4.8 A in Standby (Typical) A power-down mode extends battery life in portable SMBus 2.0 Compliant interface applications. Programmable Temperature Conversion Rate Each part number may be configured to respond to one Small 6-lead TSOT package of four separate SMBus addresses.
