Precision three-channel current and voltage monitor
The Texas Instruments INA3221AIRGVR is a three-channel, high-side current and voltage monitor. Its ±0.25% accuracy holds over the full -40°C to 125°C range. The 0V to 26V common-mode input range covers 24V industrial rails with headroom for transients.
Package and mounting — what the 16-VQFN exposed pad means for your board
The 16-VQFN Exposed Pad package measures 4x4 mm and requires a thermal land on the PCB for both heat sinking and electrical ground connection. The exposed pad is the primary thermal path.
Lifecycle and sourcing — active, no end-of-life pressure
TI lists the INA3221AIRGVR as Active with ROHS3 compliance.
