VALUE
The Power Register records power in watts by multiplying the values of the current with the value of the bus
voltage according to the equation:
Current Register 07h (Read-Only)
Full-scale range and LSB depend on the value entered in the Calibration Register. See the Programming the
TMP512/13 Power Measurement Engine section. Negative values are stored in twos complement format.
