Current Monitor Regulator High-Side 10mA 10-VSSOP
The INA229AIDGST is a high-precision digital power monitor designed for accurate measurement of shunt voltage, bus voltage, current, power, energy, and charge in low- and high-side sensing applications. The device integrates a low-offset delta-sigma analog-to-digital converter with programmable calibration and alert functionality, enabling precise system-level power monitoring in industrial, automotive, telecommunications, server, and battery-powered applications.
The device communicates through a high-speed I²C- and SMBus-compatible serial interface and supports wide common-mode voltage operation for flexible integration into multi-rail power systems. Internal computation engines provide direct digital reporting of current, power, accumulated energy, and charge values, minimizing host processor overhead.
The INA229AIDGST includes programmable conversion timing, averaging modes, alert outputs, and diagnostic monitoring features to support advanced power management and protection architectures. Its low input offset and high measurement accuracy make it suitable for precision instrumentation, energy metering, and power optimization systems.
