Texas Instruments INA260 Digital Current/Power Monitor

Texas Instruments INA260 Digital Current/Power Monitor comes with an I²C and SMBus™-compatible interface with an integrated precision shunt resistor. This device enables high-accuracy current and power measurements and over-current detection at common-mode voltages. These voltages can vary from 0V to 36V, independent of the supply voltage. The device is a bidirectional, low- or high-side, current-shunt monitor that measures the current flowing through the internal current-sensing resistor. The integration of the precision current-sensing resistor provides calibration-equivalent measurement accuracy with ultra-low temperature drift performance. This feature ensures that an optimized Kelvin layout for the sensing resistor is always obtained. The Texas Instruments INA260 features up to 16 programmable addresses on the I²C-compatible interface. The digital interface allows programmable alert thresholds, analog-to-digital converter (ADC) conversion times, and averaging. An internal multiplier enables direct readouts of current in amperes and power in watts to facilitate ease of use.
