LED Display
The PM9106AP has an on-board LED display comprising 5 (7 segment) common
cathode digits, as well as a sign LED.
The sign LED is addressed by DIG [5], the most significant digit by DIG [4] and the
least significant digit by DIG [0].
The position of the segments a, b, c, d, e, f and g are given in the diagram below:

Electrostatic Discharge (ESD) Protection
The device's inputs/outputs are protected against ESD according to Mil-Std 883C,
method 3015. The modules resistance to transients will be dependant upon the
protection components used.
Power Consumption
The overall power consumption rating for this power metering application (Figure 2),
is under 800mW, excluding the current sensor.
Circuit Description
The Application Circuit (Figure 2) shows the components required for the Watt
measurement module, using a shunt resistor for current sensing.
