EMC1704-2-AP-TR

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.
