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

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

operates as a thermostat with programmable threshold

and hysteresis. The

as a maskable SMBus alert with programmable

window comparator limits, or as a second

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.
