The Microchip 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/under voltage, over/undercurrent and overpower against user programmed limits for each channel and generate ALERT outputs.

High-side/low-side current monitor
Voltage monitor with wide vbus range
1% power measurement accuracy over a wide dynamic range
User programmable sampling rates of 8, 64, 256, 1024 SPS
16-bit resolution
External senses resistor sets the full-scale current range
