Current-Sense and Internal 1°C Temperature Monitor 12-Pin QFN T/R

The EMC1701 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. The EMC1701 also measures the source voltage and uses these measured values to present a proportional power calculation. The EMC1701 contains additional bi-directional peak detection circuitry to flag instantaneous current spikes with programmable time duration and magnitude threshold. Finally, the EMC1701 includes an internal diode channel for ambient temperature measurement.
