INA236 Overview
Description
The INA236 device is a 16-bit digital current monitor with an I2C/SMBus-compatible interface that is compliant 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.
