EMC1701 High-Side Current-Sense and Internal
1В°C Temperature Monitor
PRODUCT FEATURES Datasheet General Description Features 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. В„ 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.
