Overview

The INA216A2YFFR is a tiny, high-side current shunt monitor designed for sensing voltages across shunts at common-mode voltages from 1.8V to 5.5V. It features a fixed gain of 50V/V and is housed in a space-saving 4-bump DSBGA package, making it ideal for highly integrated mobile and handheld electronics.

Why Choose This Part

This monitor offers an ultra-low quiescent current of 25uA, which minimizes the impact on battery life in portable applications. Its DSBGA footprint of approximately 0.79mm x 0.79mm allows for placement in very tight PCB layouts where traditional SOT or MSOP packages will not fit.

Applications

Smartphones and Tablets
Monitoring battery discharge currents and charging rates in extremely space-constrained mobile designs.
Notebook Power Management
Providing precise current sensing for system-level power rails and CPU power delivery monitoring.
Telecom Equipment
Implementing high-side current monitoring for line cards and small-form-factor networking hardware.
Battery Chargers
Feedback control for precision charging circuits where low power consumption and high accuracy are required.

Getting Started

To evaluate this part, use a breakout board or the INA216EVM evaluation module to verify gain accuracy and common-mode rejection. Ensure that the shunt resistor is placed close to the IN+ and IN- pins to minimize trace resistance errors, and keep the bypass capacitor near the supply pin.
