3 Description
The INA3221 is a three-channel, high-side current
and bus voltage monitor with an I
2C- and SMBUScompatible
interface. The INA3221 monitors both
shunt voltage drops and bus supply voltages, in
addition to having programmable conversion times
and averaging modes for these signals. The INA3221
offers both critical and warning alerts to detect
multiple programmable out-of-range conditions for
each channel.
The INA3221 senses current on buses that can vary
from 0 V to 26 V. The device is powered from a
single 2.7-V to 5.5-V supply, and draws 350 μA (typ)
of supply current. The INA3221 is specified over the
operating temperature range of –40°C to +125°C.
