3 Description

The INA260 is a digital-output, current, power, and

voltage monitor with an I2C and SMBus™-compatible

interface with an integrated precision shunt resistor. It

enables high-accuracy current and power

measurements and over-current detection at

common-mode voltages that can vary from 0 V to 36

V, independent of the supply voltage. The device is a

bidirectional, low- or high-side, current-shunt monitor

that measures 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 and ensures

that an optimized Kelvin layout for the sensing

resistor is always obtained.

The 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. To facilitate ease of use, an internal

multiplier enables direct readouts of current in

amperes and power in watts.

The device operates from a single 2.7-V to 5.5-V

supply, drawing 310 μA (typical) of supply current.

The INA260 is specified over the operating

temperature range between –40°C and +125°C and

is available in the 16-pin TSSOP package.
