INA216A4YFFT

Current Regulation/Management Overview

The INA216A4YFFT is a quad, low-side current shunt monitor manufactured by Texas Instruments. It features four independent channels designed for high-precision current sensing applications. The device operates with a supply voltage range of 2.7V to 5.5V and supports input common-mode voltages from -0.3V to 26V. Each channel provides an analog output proportional to the voltage drop across an external shunt resistor. The component utilizes a small-scale surface-mount package suitable for space-constrained designs.

Current Regulation/Management Feature Summary

• Quad-channel architecture providing four independent current monitoring paths within a single integrated circuit
• High accuracy performance with specified offset voltage and gain error characteristics for precise measurement
• Wide common-mode voltage range allowing compatibility with various system power rails
• Low-power operation optimized for battery-powered and energy-efficient electronic systems

Current Regulation/Management Applications

• Battery management systems in portable electronics
• Overcurrent protection circuits in industrial equipment
• Current monitoring in consumer appliances
• Power distribution units requiring multi-channel sensing

Current Regulation/Management Procurement Notes

Verify the specific suffix YFFT corresponds to the required tape-and-reel packaging quantity and temperature grade. Confirm that the pinout matches your PCB footprint design. Ensure the operating temperature range meets your environmental specifications. Cross-reference the datasheet revision date to ensure compliance with latest electrical characteristics. Validate supplier authenticity through authorized distribution channels.

Current Regulation/Management Selection Notes

Select this component when multiple independent current channels are required in a compact form factor. Consider the trade-off between the fixed gain options and required measurement resolution. Evaluate the board space constraints against the available package types. Assess the system's common-mode voltage levels to ensure they fall within the specified operational limits. Compare power consumption requirements against other available quad monitors.

Current Regulation/Management Part Context

This part belongs to the INA216 family of current shunt monitors. The family offers variations in channel count and package styles. The A4 variant specifically denotes the quad configuration. Other members may include dual or single channel versions. The series is designed for general-purpose current sensing tasks.

Current Regulation/Management Replacement Considerations

Direct replacements must match the quad-channel configuration and similar electrical parameters. Verify pin-to-pin compatibility if substituting directly on existing boards. Check for equivalent gain accuracy and bandwidth specifications. Ensure the replacement part supports the same supply voltage range.
