Figure 32 also includes the shortcircuit latchoff phase generation. The difference between behaviors in BO or
shortcircuit, is the lack of latchoff phase in brownout conditions: V
CC
ramps up and down between VCC
ON
and VCC
OFF
in BO, whereas it goes down to 7 V and up to 15 V in shortcircuit conditions. Figure 36 shows how V
CC
moves when a
shortcircuit is detected. In BO conditions, the PFC is disabled as in UVLO conditions.
