EMC1002 1°C Dual SMBus Sensor with Resistance Error Correction PRODUCT FEATURES Data Brief General Description Features The EMC1002 is an SMBus temperature sensor that monitors up to two temperature zones and can generate two system interrupts. With ±1 °C measurement accuracy, the EMC1002 provides a low-cost solution for critical temperature monitoring applications. Extended features include automatic resistance error correction and programmable ideality factor configuration eliminating both major sources of temperature m e a s u r e m e n t e r r o r. 1 T h e 11 - b i t s i g m a d e l t a temperature-to-digital converter provides superb linearity, excellent noise immunity and repeatable temperature readings. ■ The EMC1002 generates two separate interrupts with programmable thermal trip points. The THERM output operates as a thermostat with programmable threshold and hysteresis. The ALERT output can be configured as a maskable SMBus alert with programmable window comparator limits, or a second THERM output. ■ The EMC1002 is pin compatible with the ADT7461, ADM1032, LM99, and the MAX6649. ■ ■ ■ ■ Resistance Error Correction Ideality Factor Configuration Select 1 of 4 SMBus addresses with external resistor Remote Thermal Zones — ±1°C Accuracy (40°C to 80°C) — 0.125°C resolution ■ Internal Thermal Zone ■ Maskable Interrupt using ALERT One-shot Command during standby Programmable temperature conversion rate Extended temperature (-64°C to 191°C) available Over-limit filtering with consecutive counter Small 8-lead SOIC or MSOP package; lead-free also available — ±3°C Accuracy (0°C to 85°C) ■ ■ ■ ■ Applications ■ ■ 1.Patents pending. ■ Desktop and Notebook Computers Smart batteries Industrial/Automotive Other Electronic Systems Simplified Block Diagram EMC1002 Address Pointer Register Switching Current Internal Temp Diode Remote Temp Register Internal Temp Register Low Limit Registers THERM Limit Register THERM Hysteresis Register Configuration Register Status Register Interrupt Masking SMBus Interface 11-bit delta-sigma ADC High Limit Registers Digital Mux DN Digital Mux Analog Mux DP Limit Comparator Conversion Rate Register SMCLK SMDATA ALERT THERM SMSC EMC1002 PRODUCT PREVIEW Revision 1.2 (04-15-05) 1°C Dual SMBus Sensor with Resistance Error Correction ORDER NUMBER(S): EMC1002-1-ACM-TR FOR 8 PIN, SOIC PACKAGE (Fixed Address, Tape and Reel) EMC1002-2-ACM-TR FOR 8 PIN, SOIC PACKAGE (Variable Address, Tape and Reel) EMC1002-1-ACZT-TR FOR 8 PIN, SOIC GREEN, LEAD-FREE PACKAGE (Fixed Address, Tape and Reel) EMC1002-2-ACZT-TR FOR 8 PIN, SOIC GREEN, LEAD-FREE PACKAGE (Variable Address, Tape and Reel) EMC1002-1-ACZB-TR FOR 8 PIN, MSOP PACKAGE (Fixed Address, Tape and Reel) EMC1002-2-ACZB-TR FOR 8 PIN, MSOP PACKAGE (Variable Address, Tape and Reel) EMC1002-1-ACZL-TR FOR 8 PIN, MSOP GREEN, LEAD-FREE PACKAGE (Fixed Address, Tape and Reel) EMC1002-2-ACZL-TR FOR 8 PIN, MSOP GREEN, LEAD-FREE PACKAGE (Variable Address, Tape and Reel) Reel size is 4,000 pieces.
