L H or L H STOP mode
Note: In STOP mode, Outputs of La+~Lc+ and La−~Lc− are all made OFF.
In BRAKE mode, outputs of La+~Lc+ are made ON. (source mode)
(3) Output circuit
As shown in the block diagram, in the output circuit, the Darlington emitters of PNP and NPN are provided on
the upper side, and the lower side is made as the open collector of NPN.
Connect the external transistor in the same manner as that of the application circuit.
