PAC1932

In Production

The PAC1932 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.
