Overview

The INA4230AIYBJR is a quad-channel, high-precision power and current monitor with a 16-bit ADC and an I2C/SMBus compatible interface. It is capable of measuring bus voltages up to 48V and features a programmable full-scale shunt voltage range of 20mV or 80mV to optimize dynamic range. The device provides integrated calculation of current, power, and energy, significantly reducing the processing overhead for the host microcontroller.

Why Choose This Part

The quad-channel integration in a compact 1.6x1.6mm DSBGA package offers extreme space efficiency for dense PCB layouts. High accuracy (0.02% typical) and programmable averaging filters ensure reliable measurements even in electrically noisy environments. The 16-pin selectable I2C addresses allow multiple devices to reside on the same bus without address conflicts.

Applications

Multi-Cell Battery Management
Monitoring individual cell strings or multiple power rails in battery packs to track state-of-charge and health.
Telecom Infrastructure
Precision power monitoring for high-density line cards and distributed power systems with high bus voltages.
Industrial Data Acquisition
Simultaneous four-channel sensing for motor control feedback and industrial process automation.
Server Power Distribution
Real-time energy logging and overcurrent protection for rack-mounted computing equipment.

Getting Started

Interface the device via I2C to a microcontroller and configure the configuration register to set the conversion times and averaging mode. Utilize the Alert pin to trigger hardware interrupts for over-limit conditions without constant polling. For rapid prototyping, look for TI evaluation modules (EVMs) compatible with the SC-70 or DSBGA footprints.
