PAC1932T-I/JQ

The PAC1932 is two-channel power and energy monitoring devices. A high-voltage multiplexer sequentially connects the inputs to a bus voltage monitor and current sense amplifier that feed high-resolution ADCs. Digital circuitry performs power calculations and energy accumulation. This enables energy monitoring with integration periods from 1 ms up to 36 hours or longer. Bus voltage, sense resistor voltage and accumulated proportional power are stored in registers for retrieval by the system master or Embedded Controller.

• High-Side current monitor with 2 channels - 100 mV full scale range for current sense voltage,16 bit resolution.
• Wide bus voltage range for voltage monitor - 0V to 32V input common-mode voltage
• Real time auto-calibration of offset and gain
• 1% power measurement accuracy over a wide dynamic range
• On-Chip accumulation of 28-bit power results for energy measurement
• SMBus address – 16 options, set with resistor
• No input filters required
