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.
1
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.
