INA220 具有12C接口的双向电流/功率监控器

The INA220 is a current shunt and power monitor with an Two-Wire interface. The INA220 monitors both shunt drop and supply voltage. A programmable calibration value, combined with an internal multiplier, enables direct readouts in amperes. An additional multiplying register calculates power in watts. The Two-Wire interface features 16 programmable addresses. The separate shunt input on the INA220 allows it to be used in systems with low-side sensing.

The INA220 senses across shunts on buses that can vary from 0V to 26V, useful for low-side sensing or CPU power supplies. The device uses a single +3V to +5.5V supply, drawing a maximum of 1mA of supply current. The INA220 operates from -40°C to +125°C.
