3 Description
The INA701 is a digital power monitor with an
integrated shunt resistor along with a 16-bit deltasigma
ADC specifically designed for current sensing
applications. The device can measure full-scale
currents up to ±6.225A, over the common-mode
voltage range of –0.3V to +40V.
The INA701 reports current, bus voltage, die
temperature, power, energy and charge accumulation
with a precision ±0.5% integrated oscillator, all
while performing the needed calculations in the
background. The integrated temperature sensor is
±3°C accurate over the junction temperature range.
The low offset and gain error drift of the INA701
allows use in systems that do not undergo
temperature calibration during manufacturing.
The device features selectable ADC conversion
times from 50μs to 4.12ms as well as sample
averaging from 1x to 1024x, which further helps
reduce the noise of the measured data and allows for
optimization of overcurrent detection windows.
The device is available in a tiny PowerWCSP
(DSBGA) package to minimize the solution size and
maximize thermal performance.
