SINGLE PHASE BIDIRECTIONAL POWER/ENERGY METERING IC WITH INSTANTANEOUS PULSE OUTPUT

South African Micro Electronic Systems 

SA9102F/SA9102H

3. Electrostatic Discharge (ESD) Protection

The SA9102F/SA9102H integrated circuits inputs/outputs are protected against

ESD.

4. Power Consumption

The power consumption rating of the SA9102F and SA9102H integrated circuits is

less than 30mW.

5. Pulse Output Signals

The calcualted power is divided down to a pulse rate of 64Hz, for rated conditions

on FOUT (Pin 12), for both the SA9102F and SA9102H.

The format of the pulse output signal, which provides power/energy and direction

information, is the only difference between the SA9102F and SA9102H devices.

The direction of the energy flow is defined by the mark/space ratio in the SA9102F,

while the pulse width defines the direction on the SA9102H.
