Summary of L6566B power management functions
It has been seen that the device is provided with a number of power management functions:
multiple operating mode upon loading conditions and protection functions. To help the
designer familiarize with these functions, in the following tables all of theme are summarized
with their respective activation mechanism and the resulting status of the most important
pins. This can be useful not only for a correct use of the IC but also for diagnostic purposes:
especially at prototyping/debugging stage, it is quite common to bump into unwanted
activation of some function, and these tables can be used as a sort of quick troubleshooting
guide.
