ina226

This project is a solution verification version design for INA220AIDGSR of Lichuang Mall .

This project is a sample project for the Solicitation Order for Lichuang EDA open source hardware platform solution verification module .

INA226 is a current shunt and power monitor with I 2 C interface. The INA226 monitors the shunt voltage drop and the bus supply voltage. Programmable Calibration • High/low low-side sensing values, transition times and averaging, combined with internal multipliers, direct readout • Reports current, voltage and supply current (amps) and power (watts). When the INA226 draws power from a supply of +2.7V to +5.5V, it can sense a bus current of 0V to +36V, drawing a typical supply current of 330µA. The specified operating temperature range of INA226 is -40℃ to +125℃. I 2 C interface with 16 programmable addresses.

0V to +36V Sense Bus Voltage High/Low Side Sensing High Accuracy: – 0.1% Gain Error (Max) – 10µV Offset (Max) • Configurable Averaging Option • 16 Programmable Addresses • In Operates from 2.7V to 5.5V power supply range • MSOP-10 package

This solution uses high-side measurement, the sampling resistor is 10 milliohms, and the collected signal is communicated with the outside through I2C.
