The EMC1033 is an SMBus temperature sensor that monitors up to three temperature zones and can generate two system interrupts. With ±1°C measurement accuracy, the EMC1033 provides a low-cost solution for critical temperature monitoring applications. Features include automatic resistance error correction and programmable ideality factor configuration eliminating both major sources of temperature measurement error1.
The EMC1033 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 as a second THERM# output. Both interrupts are maintained in an 8-pin package while a third temperature zone is added with the anti-parallel diode technique. This allows the EMC1033 to be pin compatible with the ADT7461, ADM1032, LM99 and the MAX6649 with the advantage of a third temperature zone.
