Power Connection
e battery is connected to the module’s B+ pin though a fuse, a diode, and a keyswitch. e fuse
protects the wiring in the event of a short or failure. e return path of the coils is also brought back
to the B+ pin to utilize the yback diodes connected inside the 1353 between B+ and each driver
output.
e keyswitch is used to turn on the system. When the keyswitch is closed, B+ goes high and the
1353’s power supply brings up the module.
