Application Implementations
Multiple Sequencer Implementations
In order to control the sequencing of more than 4 voltages,
several of the ISL6123, ISL6124, ISL6125 or ISL6127
devices can be variously configured together to accomplish
this. There may be concerns of a particular implementation
that would make a particular configuration preferable over
another. The fundamental questions to answer to determine
which configuration is best suited for your applications are:
1. What level of voltage assurance is needed prior to
sequencing on and can the voltage supplies be grouped
into high and low criticality
2. Is there a critical maximum time window all supplies must
be present at load or is there a first and a second group
preference possibly with some work done in between the
two groups of voltages being present
Three configurations are described and illustrated here.
In applications where the integrity of critical voltages must be
assured prior to sequencing, additional monitoring of the
critical supplies is needed. If the compliance of the voltage is
critical for either undervoltage and/or overvoltage, the
ISL613X family of supervisors can be employed to provide
this additional assurance across multiple sequencers. See
document FN9115 for supervisor data sheet. Figure 17 is a
block diagram of this voltage compliant, high assurance, low
risk configuration showing the ISL613X supervisor and a mix
of FET switched outputs and logic output sequencers
(ISL6124 and ISL6125 ICs).
