Application Implementations
Multiple Sequencer Implementations
The ISL6123, ISL6124, ISL6125 and ISL6127 devices can be
configured to control sequencing of more than four voltages. A
particular configuration may be preferable to another, depending
on concerns. The fundamental questions 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 in which 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?
17
Three configurations are described and illustrated here.
In applications for which the integrity of critical voltages must be
assured prior to sequencing, additional monitoring of the critical
supplies is needed. If voltage compliance is critical for either
undervoltage or overvoltage, voltage supervisors can be used to
provide this additional assurance across multiple sequencers.
Figure 19 is a block diagram of a voltage-compliant,
high-assurance, low-risk configuration showing the ISL6131 or
ISL6132 supervisor and a mix of FET switched outputs and logic
output sequencers (ISL6124 and ISL6125 ICs).
