INA3221AIRGVR
by TI(德州仪器)Monitoring several power rails is a typical role for TI's INA3221AIRGVR, a multichannel current and bus-voltage monitor. It measures shunt voltage and bus voltage, making it useful for observing power consumption in embedded equipment. This record uses a surface-mount QFN footprint with an exposed pad. Its KiCad download pairs a 17-pin symbol with QFN-16_L4.0-W4.0-P0.65-TL-EP2.2, containing 17 pads, and includes a 3D model for mechanical review. A real ProtoFlow import supplied the files; the conversion was checked in the editor. The part can be opened directly in ProtoFlow for schematic placement and board layout.
