Overview

The INA236AIYBJR is a high-precision, 16-bit digital current, voltage, and power monitor with an I2C/SMBus-compatible interface. It features a wide common-mode range of 0V to 48V and provides programmable full-scale ranges of 20mV or 80mV to maximize dynamic range across different shunt resistor values.

Why Choose This Part

This monitor offers exceptional precision with a 16-bit ADC and integrated averaging, significantly reducing the host microcontroller workload. Its ultra-compact 8-DSBGA package and low 300uA operating current make it ideal for space-constrained, power-sensitive designs.

Applications

Smart Battery Packs
Precisely monitoring charge and discharge currents in multi-cell battery systems with high side sensing up to 48V.
Power Distribution Units (PDUs)
Real-time power monitoring and over-current protection for data center or industrial rack equipment.
Motor Control Feedback
Monitoring phase current or bus voltage in small motor drives to ensure operational efficiency and safety.
Energy Management Systems
Aggregating power usage data across multiple nodes in industrial automation environments using selectable I2C addresses.
