INA236 Overview
The INA236 device is a 16-bit digital current monitor with an I2C/SMBus-patible interface that is pliant with a wide range of digital bus voltages such as 1.2 V, 1.8 V, 3.3 V, and 5.0 V. The device monitors the voltage across an external sense resistor and reports values for current, bus voltage, and power.
