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 bus 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.

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.
