EL7585A
In some circumstances, (depending on ambient temperature
and thermal design of the board), continuous operation at
current limit may result in the over-temperature threshold
being exceeded, which will cause the part to disable
immediately.
All I/O also have ESD protection, which in many cases will
also provide overvoltage protection, relative to either ground
or V DD . However, these will not generally operate unless
abs max ratings are exceeded.
Component Selection for Start-Up Sequencing and
Fault Protection
The C REF capacitor is typically set at 220nF and is required
to stabilize the V REF output. The range of C REF is from
22nF to 1μF and should not be more than five times the
capacitor on C DEL to ensure correct start-up operation.
The C DEL capacitor is typically 220nF and has a usable
range from 47nF minimum to several microfarads - only
limited by the leakage in the capacitor reaching μA levels.
C DEL should be at least 1/5 of the value of C REF (See
above). Note with 220nF on C DEL the fault time-out will be
typically 50ms and the use of a larger/smaller value will vary
this time proportionally (e.g. 1μF will give a fault time-out
period of typically 230ms).

Fault Sequencing
The EL7585A has an advanced fault detection system which
protects the IC from both adjacent pin shorts during
operation and shorts on the output supplies.
A high quality layout/design of the PCB, in respect of
grounding quality and decoupling is necessary to avoid
falsely triggering the fault detection scheme - especially
during start-up. The user is directed to the layout guidelines
and component selection sections to avoid problems during
initial evaluation and prototype PCB generation.
