(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 2.2K

Ω - 180KΩ, recommended 100KΩ.

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.
