36V、双方向、超高精度、ローまたはハイサイド、I2C 出力電流/電力モニタ、アラート付き - INA226
 

概要

The INA226 is a current shunt and power monitor with an I2C™- or SMBUS-compatible interface. The device monitors both a shunt voltage drop and bus supply voltage. Programmable calibration value, conversion times, and averaging, combined with an internal multiplier, enable direct readouts of current in amperes and power in watts.

The INA226 senses current on common-mode bus voltages that can vary from 0 V to 36 V, independent of the supply voltage. The device operates from a single 2.7-V to 5.5-V supply, drawing a typical of 330 µA of supply current. The device is specified over the operating temperature range between –40°C and 125\xC2°C and features up to 16 programmable addresses on the I2C-compatible interface.
