TIINA231AIYFFR
Overview
The INA231AIYFFR is a high-side or low-side current-shunt and power monitor with an I2C-compatible interface, featuring a 16-bit ADC for precise measurements. It monitors both shunt voltage drops and bus supply voltages, providing real-time calculations of power, current, and voltage for systems operating between 0V and 28V. Its ultra-compact 12-DSBGA package and low power consumption make it ideal for space-constrained, battery-operated devices.
Why Choose This Part
The device offers high precision with +/-0.5 percent accuracy and a 16-bit resolution ADC, ensuring reliable data for sensitive power management tasks. Its low quiescent current of 330 uA (typical) and a 3 uA sleep mode minimize the impact on battery life, while the configurable averaging and programmable alert thresholds allow for flexible system monitoring without constant CPU polling.
Applications
Key Specifications
Getting Started
Engineers can evaluate this part using Texas Instruments' INA231EVM evaluation module. Integration involves connecting the I2C interface to a microcontroller and configuring the 16-bit registers for shunt resistance and averaging modes; ensure the 0.4mm pitch DSBGA package is handled using high-density PCB design rules.
