Overview

The INA233AIDGSR is a 16-bit high-side or low-side current, voltage, and power monitor featuring an integrated power accumulator for energy calculation. It operates over a bus voltage range of 0V to 36V and includes a PMBus-compliant interface for simplified integration into power management systems.

Why Choose This Part

The device features 0.1 percent accuracy and a dedicated power accumulator that offloads energy integration tasks from the host processor. Its PMBus interface and 16 programmable addresses make it highly scalable for complex systems with multiple power rails.

Applications

Server Power Monitoring
Precise monitoring of high-current rails with energy accumulation for data center efficiency analysis.
Battery Management Systems
Tracking state-of-charge and state-of-health in multi-cell packs via high-accuracy current and voltage measurement.
Telecom Infrastructure
Real-time power monitoring and fault detection using the PMBus alert pins for system protection.
