Data Sheets:
The PAC1951 is a power monitor and energy monitor that reports on bus voltage and sense voltage 16-bits of resolution. Power is reported as a simultaneous product of two 16-bit independent bus and sense voltages. All registers are accessible through I2C / SMBus including an 8 sample average for reading stability. The device can detect over/undervoltage, over/undercurrent and overpower against user programmed limits for each channel and generate ALERT outputs.
There are two versions of the PAC1951: the PAC1951-1 devices are for high-side current sensing and the PAC1951-2 devices are for low-side current sensing.
- High-Side/Low-Side Current Sensor
- 100 mV Full-Scale Range to Sense Current (Configurable to 50 mV)
- 16-Bit Resolution Sense Current
- External Sense Resistor Sets the Full-Scale Current Range
- Very Low Input Current Simplies Routing
- Voltage Monitor with Wide VBUS Range
- 0V to 32V Full Scale Range (Configurable to 16V)
- 16-Bit Resolution for Voltage Measurements
- Real-Time Auto-Calibration of Offset Error for Voltage and Current
- 1% Power Measurement Accuracy Over a Wide Dynamic Range
- On-Chip Accumulation of 30-Bit Power Results for Ennergy Measurement
- User Programmable Sampling Rate: 8, 64, 256, 1024 SPS
- 5120 SPS for Burst Mode
- 2.7V to 5.5V Supply Operation
- 1.62-5.5V Capable I2C/SMBus and Digital I/O
- SMBus 3.1 and I2C Fast Mode Plus, 1 Mbps
- High Speed Mode (3.4 Mbps)
- ALERT on Over/Undervoltage and Current or Overpower Conditions
- Two Independent ALERT/GPIO Pins
- Coulomb Counting: When Selected, the Accumu lator Accumulates VSENSE Values
