EMC1188
Quad Channel 1°C Temperature Sensor with Hardware
Thermal Shutdown and 1.8V SMBus Communications
PRODUCT FEATURES Datasheet General Description Applications The EMC1188 is a high accuracy, low cost, 1.8V System
Management Bus (SMBus) compatible temperature sensor.
Advanced features such as Resistance Error Correction (REC),
Beta Compensation (to support CPU diodes requiring the
BJT/transistor model including 65nm and lower geometry
processors) and automatic diode type detection combine to
provide a robust solution for complex environmental monitoring
applications. The ability to communicate at 1.8V SMBus levels
provides compatible I/O for the advanced processors found in
today’s tablet and smartphone applications.  The EMC1188 monitors four temperature (three external and
one internal) channels, providing ±1°C accuracy for both
external and internal diode temperatures.
Additionally, the EMC1188provides a hardware programmable
system shutdown feature that is programmed at part power-up
via two pull-up resistor values and that cannot be masked or
corrupted through the SMBus.
REC automatically eliminates the temperature error caused by
series resistance allowing greater flexibility in routing thermal
diodes. Frequency hopping* and analog filters ensure remote
diode traces can be as far as eight (8) inches without degrading …
