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.
