INA228AQDGSRQ1 Product Overview
INA228AQDGSRQ1 is an automotive-qualified, high-precision digital power monitor from Texas Instruments. It measures shunt voltage, bus voltage and temperature, then calculates current, power, energy and charge through an I²C/SMBus-compatible interface.
The device uses a 20-bit measurement architecture and supports common-mode voltages up to 85V, making it suitable for accurate monitoring of high-side or low-side power rails. The description below is based on Texas Instruments INA228-Q1 product information; verify the complete orderable-part data before design-in.
