INA216A1YFFT

Current Regulation/Management Overview

The INA216A1YFFT is a high-precision, unidirectional current shunt monitor manufactured by Texas Instruments. It operates from a single +1.8V to +5.5V power supply and draws a maximum of 3μA supply current. The device features a common-mode range of +1.8V to +5.5V and is housed in a 4-pin DSBGA (YFF) package. It is specified for operation over an extended temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Zero-drift architecture ensures high precision without external calibration
• Low-power design with minimal supply current consumption
• High-side sensing capability within the full common-mode voltage range

Current Regulation/Management Applications

• Battery management systems
• Overcurrent protection circuits
• Load switch control

Current Regulation/Management Procurement Notes

Verify component authenticity through authorized distributors. Confirm package marking matches the YFF designation. Check lifecycle status as the part may be scheduled for obsolescence. Ensure storage conditions comply with moisture sensitivity levels for the DSBGA package. Validate that the specific suffix corresponds to the tape-and-reel configuration if required.

Current Regulation/Management Selection Notes

Select this component when high accuracy is required in low-voltage applications. The zero-drift technology eliminates the need for offset trimming. Consider the small footprint for space-constrained designs. Verify that the input common-mode voltage aligns with the system's rail voltages. Evaluate thermal performance given the operating temperature range.

Current Regulation/Management Part Context

This part belongs to the INA216 family of current shunt monitors. It is designed for applications requiring precise current measurement in portable and battery-powered devices. The family offers various packages and output configurations to suit different board layout constraints.

Current Regulation/Management Replacement Considerations

Check for direct pin-compatible substitutes within the same manufacturer's portfolio. Verify electrical specifications match exactly before substitution. Consider newer generations if available, noting potential parameter differences.
