User Guide:
The PAC1941 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 PAC1941: the PAC1941-1 devices are for high-side current sensing and the PAC1941-2 devices are for low-side current sensing.
- High-Side/Low-Side Current Monitor
- 100 mV Full-Scale Range (Configurable for 50 mV)
- 16-Bit Resolution
- External Senss Resistor Sets the Full-Scale Current Range
- Very Low Input Current Simplifies Routing
- Voltage Monitor with Wide VBUS Range
- 0 to 9V Full-Scale Range (Configurable to 4.5V)
- 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 Energy Measurement
- User Programmable Sampling Rates of 8, 64, 256, 1024
