EMC1704 High-Side Current-Sense and Multiple
1В°C Temperature Monitor
PRODUCT FEATURES Datasheet General Description Features The EMC1704 is a combination high-side current sensing
device with precision temperature measurement. It
measures the voltage developed across an external sense
resistor to represent the high-side current of a battery or
voltage regulator. It also measures the source voltage and
uses these measured values to present a proportional
power calculation. The EMC1704 contains additional bidirectional peak detection circuitry to flag instantaneous
current spikes with programmable time duration and
magnitude threshold. Finally, the EMC1704 includes up to
three (3) external diode channels and an internal
temperature sensor for temperature measurement. пЃ® High-side current sensor пЃ® Independent hardware set instantaneous current peak
detector (EMC1704-2 only) The temperature measurement includes advanced features
such as Resistan ce Error Correctio n (REC), Beta
Compensation (to support CPU diodes requiring the
BJT/transistor model including 45nm and 65nm
processors), and automatic diode type detection.
Both current sensing and temperature monitoring include
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 causes the THERM pin to be asserted. Applications
