Microchip PAC1933T-I/JQ, Current Monitor 16-Pin, UQFN

The PAC1933 is a three-channel 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.
