Application Notes:
The PAC1942 is a dual 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 PAC1942: the PAC1942-1 devices are for high-side current sensing and the PAC1942-2 devices are for low-side current sensing.
- Dual High Side Power Monitor (PAC1942-2 is a Low Side)
- 100 mV Full Scale Range for Current Sense Voltage (Configurable to 50mV)
- 16-bit Resolution
- External Sense Resistor Sets the Full-Scale Current Range
- Very Low Input Current Simplifies Routing
- Voltage Monitor with Wide VBUS Range
- 0V to 9V FSR (Configurable to 4.5V)
- 16-bit Resolution
- 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
- Uster Programmable Sampling Rate 8, 64, 256, 1024
- 5120 SPS for a Single Channel in 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, 1Mbps
- High Speed Mode (3.4 Mbps)
- ALERT on Over/UnderVoltage and Current or Overpower
- Two Independent ALERT/GPIO pins
- Coulomb Counting: When Selected, the Accumu lator Accumulates VSENSE Values
