Product description
INA231 high side or
low side measurement, bidirectional current and power monitor with 1.8V I2C
interface
INA231
is a current shunt and power monitor with a 1.8V I2C compatible interface (with
16 programmable addresses). The INA231 monitors shunt voltage drop and bus power
supply voltage, providing enhanced protection by setting the ALERT pin to active
when the corresponding value exceeds the programmed range.
Programmable
calibration values, conversion times, and averaging can be used in conjunction
with an internal multiplier to achieve direct reading of current values (in
amperes) and power values (in watts), thereby reducing host processing
load.
The
INA231 detects the current on the bus voltage (between 0V and 28V). The device
is powered by a single power supply of 2.7V to 5.5V, and consumes a power supply
current of 330 μ A (typical value). The INA231 has a rated operating temperature
range of - 40 ° C to+125 ° C.
The
INA231 has two versions: the INA231A performs continuous switching of shunt and
bus voltage during startup, while the INA231B starts in a low current shutdown
mode. This module uses the INA231A version.
