EMC1702 High-Side Current-Sense and Dual
1В°C Temperature Monitor
PRODUCT FEATURES Datasheet General Description Features The EMC1702 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 EMC1702 contains additional bidirectional peak detection circuitry to flag instantaneous
current spikes with programmable time duration and
magnitude threshold. Finally, the EMC1702 includes an
external diode channel for temperature measurement as
well as an internal diode for ambient temperature
measurements. В„ The temperature measurement includes advanced features
such as Resistance Error Correction (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
