INA745x/INA745x-Q1 Digital Power Monitor

Texas Instruments INA745x/INA745x-Q1 I²C-Output Digital Power Monitor has an integrated current-sensing element and a 16-bit delta-sigma ADC specifically designed for current-sensing applications. The device can measure full-scale currents up to ±39.32A with common-mode voltage support from –0.1V to +40V. The INA745x/INA745x-Q1 reports current, bus voltage, die temperature, power, energy, and charge accumulation while employing a precision ±0.5% integrated oscillator, all while performing the needed calculations in the background. The integrated temperature sensor is ±2.5°C accurate over the junction temperature range.
