PM9106AP
2. 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:

3. 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.
4. Power Consumption
Theoverallpowerconsumptionratingforthispowermeteringapplication(Figure2),
is under 800mW, excluding the current sensor.
5. Circuit Description
The Application Circuit (Figure 2) shows the components required for the Watt
measurement module, using a shunt resistor for current sensing.
