Functional description
Basic structure
The L9935 is a dual full bridge driver for inductive loads with a chopper current regulation.
Outputs A1 and A2 belong to full bridge A Outputs B1 and B2 belong to full bridge B.
The polarity of the bridges can be controlled by bit0 and bit3 (for full bridge A, bit3, for full
bridge B, bit0). Bit5, bit4 (for full bridge A) and bit2, bit1 (for full bridge B) control the
currents. Bit3 high leads to output A1 high. Bit0 high leads to output B1 high.
