View Side By Side Comparison

The PAC1934 is a four channel power/energy monitor with current sensor amplifier and bus voltage monitors that feed high resolution ADCs.  Digital circuitry performs power calculations and energy accumulation.  The PAC1934 enables energy monitoring with integration periods from 1 ms to up to 36 hours.  Bus voltage, sense resistor voltage, and accumulated proportional power are stored in registers for retrieval by the system master or embedded controller.

The sampling rate and energy integration period can be controlled over SMBus or I2C.  Active channel selection, one-shot measurements, and other controls are also configurable.  The PAC1934 uses real time calibration to minimize offset and gain errors.  No input filters are required for this device.
