The INA234AIYBJR is a Texas Instruments current, voltage and power monitor with an alert output, supplied in an 8-pin chip-scale surface-mount package. Monitors of this type integrate a current-sense amplifier, an analog-to-digital converter and power-calculation registers behind an I2C-compatible digital interface, so the host reads bus current, bus voltage and computed power directly instead of conditioning a shunt signal in discrete analog circuitry. The alert pin lets the device flag an out-of-range condition without the host polling it. The INA234AIYBJR is in active production at Texas Instruments.

Digital power monitors are designed into rail-level telemetry: measuring how much current and power each board, module or subsystem draws so firmware can enforce budgets, detect faults and log consumption. Common settings are server and networking line cards, telecom and industrial equipment, battery-powered systems and test instrumentation. Because current, voltage and power arrive as register reads over I2C, the design avoids a separate op-amp, ADC and calibration path per rail. Note that this catalogue record carries only packaging and lifecycle attributes, so consult the Texas Instruments datasheet for electrical limits before designing it in.
