Description
General part information
PAC1951 Series
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.
