PRODUCT FEATURES

GENERAL DESCRIPTION

FEATURES

Supports two External Temperature Diodes

The EMC1053 is a System Management Bus (SMBus)

temperature sensor that monitors three temperature

zones, one internal diode and two externally connected

diodes, for PC and embedded environments. The

EMC1053 includes resistance error correction and

ideality factor configuration to eliminate major sources of

temperature measurement error.¹

—

±1°C Accuracy (40°C to 80°C)

0.125°C Resolution

Ideality Factor Configuration

Accepts 2200pF Cap Across External Diodes for Noise

Suppression

—

Optional Resistive Error Correction on External Diode 2

Resistive Error Correction (up to 100 Ohms)

Selectable Beta Compensation for Substrate Diodes

An added feature to the EMC1053 is a function that

automatically compares the two external temperature

zones and reports the hotter of the two temperatures.

Selectable conversion rates and standby mode support

low-power operation. The temperature measurement

ranges support two data ranges (and formats), -64°C to

+127°C and -64°C to +191°C.

Internal Temperature Diode

—

±3°C Accuracy (0°C to 85°C)

0.125°C Resolution

Low Power Operation

—

4uA Standby Current

3.0V to 3.6V Supply

Programmable Conversion Rate

SMBus 2.0 Compliant
