The PAC1931 is a single 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.
Additional Features
100mV full scale range for current sense voltage
Selectable bidirectional measurment capability
0 to 32V input commen-mode voltage
External sense resistor sets full scale current range
1% power measurement accuracy over a wide dynamic range
On-chip accumulation of 28-bit power results for engergy measurement
48-bit power accumulator register
Sampling rates of 8, 64,256, and 1024 samples per second
At least 17 minutes of power accumulation data at 1024 samples per second
2.7V to 5.5V operation
Separate Vdd for I/O pin
1.62-5.5V capable SMBus and digital I/O
SMBus 3.0 and I2C Fast Mode Plus
WLCSP 2.225 x 2.17
