The EMC1002 is an SMBus temperature sensor that monitors up to two temperature zones and can generate two system interrupts. With ±1 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 measurement error1. The 11-bit sigma delta temperature-to-digital converter provides superb linearity, excellent noise immunity and repeatable temperature readings.

The EMC1002 generates two separate interrupts with output programmable thermal trip points. The THERM operates as a thermostat with programmable threshold and hysteresis. The ALERT output can be configured as a maskable SMBus alert with programmable output. window comparator limits, or a second THERM The EMC1002 is pin compatible with the ADT7461, ADM1032, LM99, and the MAX6649.
