Adjustable Quad Sequencer
The ISL8700, ISL8701, ISL8702, ISL8702A, ISL8703,
ISL8704, ISL8705 family of ICs provide four delay adjustable
sequenced outputs while monitoring an input voltage all with
a minimum of external components.
High performance DSP, FPGA, P and various subsystems
require input power sequencing for proper functionality at
initial power up and the ISL870X provides this function while
monitoring the distributed voltage for over and undervoltage
compliance.
The ISL8700 and ISL8701 operate over the +2.5V to +24V
nominal voltage range, whereas the ISL8702 operates over
the 2.5V to +12V range. All three have a user adjustable
time from UV and OV voltage compliance to sequencing
start via an external capacitor when in auto start mode and
adjustable time delay to subsequent ENABLE output signal
via external resistors.
Additionally, ISL8702A, ISL8703, ISL8704 and ISL8705
provide I/O for sequencing on and off operation (SEQ_EN)
and for voltage window compliance reporting (FAULT) over
the +2.5V to +24V voltage range. The ISL8702 also has this
feature but operates over the 2.5V to +12V range.
Easily daisy chained for more than 4 sequenced signals.
Altogether, the ISL870X provides these adjustable features
with a minimum of external BOM. See Figure 1 for typical
implementation.

NOTES:
1. Part Numbers in Bold are available now, others will soon be available,
contact factory for availability schedule.
2. Intersil Pb-free plus anneal products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible with
both SnPb and Pb-free soldering operations. Intersil Pb-free products
are MSL classified at Pb-free peak reflow temperatures that meet or
exceed the Pb-free requirements of IPC/JEDEC J STD-020.
