EMC1002
1C Dual SMBus
Sensor with Resistance
Error Correction
General Description
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.

T h e 11 - b i t s i g m a d e l ta
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.
