Application information
L6563 - L6563A
30/37
IC shutdown upon brownout can be easily realized as shown in
Figure 44
The scheme on
the left is of general use, the one on the right can be used if the bias levels of the multiplier
and the R
FF
·C
FF
time constant are compatible with the specified brownout level and with the
specified holdup time respectively.
In it is possible to find a summary of all of the above mentioned working conditions that
cause the device to stop operating.
