EMC1033
1°C Triple SMBus
Sensor with Resistance
Error Correction
PRODUCT FEATURES
General Description
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 error.

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.
