Function
Power Output Bridge A Output 2.
Output
Charge Pump Oscillator Output.
Logic Input
Reset Pin. LOW logic level restores the Home State
(State 1) on the Phase Sequence Generator State
Machine.
If not used, it has to be connected to +5V.
Analog Input Bridge A Current Controller Reference Voltage.
Do not leave this pin open or connected to GND.
(6) Also connected at the output drain of the Over current and Thermal protection MOSFET. Therefore, it has to be driven putting in series
a resistor with a value in the range of 2.2KΩ - 180KΩ, recommended 100KΩ.
