Logic Input (6)
Bridge A Enable. LOW logic level switches OFF all Power
MOSFETs of Bridge A. This pin is also connected to the
collector of the Overcurrent and Thermal Protection
transistor to implement over current protection.
If not used, it has to be connected to +5V through a
resistor.
Analog Input Bridge A Current Controller Reference Voltage.
Do not leave this pin open or connect 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 - 47KΩ, recommended 33KΩ.
