INA231BIYFDT

Current Regulation/Management Overview

The INA231BIYFDT is a bidirectional current and power monitor manufactured by Texas Instruments, featuring a 1.8-V I²C-compatible interface with 16 programmable addresses. It supports high-side or low-side sensing for bus voltages ranging from 0 V to 28 V. The device operates on a single supply voltage between 2.7 V and 5.5 V, consuming a typical supply current of 330 µA. It provides direct digital readings of current in amperes and power in watts through programmable calibration values and internal multipliers. The component is rated for an operating temperature range of -40°C to +125°C and utilizes a 12-DSBGA package.

Current Regulation/Management Feature Summary

• Bidirectional current and power monitoring capability with high-side or low-side measurement support
• Integrated 1.8-V I²C interface allowing for direct digital reporting of current and power values
• Configurable alert pin functionality that triggers when sensed values exceed programmed thresholds
• Programmable conversion time and averaging options to reduce host processor load

Current Regulation/Management Applications

• High-side or low-side current monitoring in industrial systems
• Power management monitoring in portable electronics
• Battery protection circuits requiring precise current tracking
• Over-current protection in server and data center power rails

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DT' against the official datasheet to confirm package type and tape/reel specifications. Confirm availability status as distribution channels may list obsolete variants. Ensure the I²C address configuration matches system requirements before integration. Check for any recent Product Change Notices regarding manufacturing site or material composition updates.

Current Regulation/Management Selection Notes

Select this component when bidirectional monitoring with direct digital output is required. The 1.8-V I/O compatibility suits low-voltage logic interfaces. Consider the INA231A variant if continuous conversion at startup is preferred over the INA231B's low-current shutdown mode. Evaluate the 12-DSBGA package constraints for PCB layout and thermal management needs.

Current Regulation/Management Part Context

The INA231 belongs to Texas Instruments' family of high-precision current shunt and power monitors. These devices are designed to simplify system design by providing calibrated digital outputs, eliminating the need for external microcontrollers to perform complex calculations. The series offers various accuracy grades and interface options to fit diverse application requirements.
