Current Sensor Breakout, Power Monitoring, Bi-Directional, INA219, 3.2A, +26Vdc,MCU-219

The MCU-219 module is a zero-drift, bi-directional current/power monitoring integrated circuit (IC) with an I2C interface. INA219 monitors the voltage drop on the shunt resistor, detect the shunt supply voltage and lastly, calculates the power supply. The device is in SOT23 package and can provide a low-cost solution for digital current sensing in servers, notebook computers, power supplies, battery management, and automotive and telecommunications equipment.  

 

A precision amplifier measures the voltage across the 0.1 ohm, 1% sense resistor. Since the amplifier maximum input difference is ±320mV this means it can measure up to ±3.2 Amps. With the internal 12 bit ADC, the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA. Advanced hackers can remove the 0.1 ohm current sense resistor and replace it with their own to change the range (say a 0.01 ohm to measure up 32 Amps with a resolution of 8mA)
