3 Description
The INA232 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.
The INA232 features programmable ADC conversion
times and averaging. The device also has a
programmable calibration value with an internal
multiplier that enables direct readouts of current in
amperes and power in watts. The device monitors
the bus voltage present on the IN– pin and can
alert on over/under current as well as over/under
voltage conditions. High input impedance while in
current measurement mode allows use of larger
current sense resistors needed to measure small
value system currents.
The INA232 senses current on common-mode bus
voltages that can vary from –0.3 V to 48 V,
independent of the supply voltage. The device
operates from a single 1.7-V to 5.5-V supply, drawing
a typical supply current of 300 μA in normal operation.
The device can be placed in a low-power standby
mode where the typical operating current is 2.2 μA.
