8.2.7 Peak Current (I1PEAK, I2PEAK ) and Peak Voltage (V1PEAK, V2PEAK )

Address: 18 (I1PEAK), 19 (V1PEAK), 22 (I2PEAK), 23 (V2PEAK)

Peak current, I1PEAK (I2PEAK) and peak voltage, V1PEAK (V2PEAK) are the instantaneous current and voltage

samples with the greatest magnitude detected during the last low-rate interval. These are two's complement

values in the range of -1.0

 value  1.0, with the binary point to the right of the MSB.

8.2.8 Apparent Power (S1, S2)

Address: 20 (S1), 24 (S2)

Apparent power S1 (S2) is the product of V1RMS and I1RMS (V2RMS and I2RMS), These are two's complement

values in the range of 0

 value  1.0, with the binary point to the right of the MSB.

8.2.9 Power Factor (PF1, PF2)

Address: 21 (PF1), 25 (PF2)

Power factor is calculated by dividing active power by apparent power. The sign is determined by the active

power sign. These are two's complement values in the range of -1.0

 value  1.0, with the binary point to the

right of the MSB.

8.2.10 Temperature (T) – Address: 27

contains results from the on-chip temperature measurement. By default, T uses the Celsius scale, and is a

two's complement value in the range of -128.0

 value  128.0 (oC), with the binary point to the right of bit 16.

can be rescaled by the application using the TGAIN and TOFF registers.

8.2.11 Active, Apparent, and Reactive Energy Pulse Outputs (EPULSE , SPULSE , QPULSE )

Address: 29 (EPULSE), 30 (SPULSE), 31 (QPULSE)

These drive the pulse outputs when configured to do so. These are two's complement values in the range of

-1.0

 value  1.0, with the binary point to the right of the MSB. Refer to 4.8 Power and Energy Results on

page 16.
