EMC1438 1°C Multiple Temperature Sensor
with Hardware Controlled Standby &
Hottest of Multiple Zones
PRODUCT FEATURES Datasheet General Description Features The EMC1438 is a high accuracy, low cost, System
Management Bus (SMBus) temperature sensor.
Advanced features such as Resistance Error Correction
(REC), Beta Compensation (to CPU diodes requiring the
BJT or transistor model) and automatic diode type
detection combine to provide a robust solution for
complex environmental monitoring applications.
Additionally, the hardware controlled STANDBY pin
allows for system level power shutdown to support
energy saving initiatives. „ Hardware Set Standby Mode „ Designed to support 45nm, 65nm, and 90nm CPU
diodes
Supports diodes requiring the BJT or transistor model
Resistance Error Correction (up to 100 Ohms)
Up to seven External Temperature Monitors The EMC1438 monitors up to eight temperature
channels (up to seven external and one internal). The
device provides ±1°C accuracy for the internal and
external diode temperatures.
Temperature monitoring includes two tiers of protection:
one that can be masked and causes the ALERT pin to
be asserted, and the other that cannot be masked and …
