INA4230AIYBJR

Current Regulation/Management Overview

The INA4230AIYBJR is a quad-channel, 16-bit high-precision current and power monitor manufactured by Texas Instruments. It operates within an input voltage range of 1.7 V to 5.5 V and supports both high-side and low-side sensing configurations. The device features a maximum accuracy of 2% and draws only 2.5 µA of operating supply current. It functions reliably across a temperature range of -40°C to +125°C and is housed in a BGA-16 surface-mount package.

Current Regulation/Management Procurement Notes

Verify the specific suffix 'AIYBJR' against official Texas Instruments documentation to confirm temperature grade, packaging type, and tape/reel specifications. Ensure compatibility with I2C bus requirements and check for any regional compliance certifications such as RoHS status before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when multiple independent current channels are required within a compact footprint. The 16-bit resolution provides detailed data for power analysis, while the wide operating voltage range accommodates various logic levels. Consider the BGA-16 package constraints during PCB layout design to ensure proper thermal dissipation and signal integrity.

Current Regulation/Management Part Context

This part belongs to the INA4230 series of current monitors, designed for applications requiring accurate measurement of multiple power rails. It integrates precision amplifiers and analog-to-digital converters into a single chip, simplifying the design of complex power management systems compared to discrete solutions.

Current Regulation/Management Replacement Considerations

Consult official substitution guides for compatible alternatives within the same family or from other manufacturers. Verify pinout compatibility and electrical parameter alignment before replacing the original component in existing designs.
