Shunt and Bus Voltage Monitor with I2C-and SMBUS-Compatible Interface
1 Features 3 Description The INA3221 is a three-channel, high-side current
and bus voltage monitor with an I2C-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. 1 Senses Bus Voltages From 0 V to 26 V
