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.
