Adjustable Quad Sequencer
The ISL8700, ISL8701, ISL8702 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, μP 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 nominal voltage 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, the ISL8702 provides an input for sequencing
on and off operation (SEQ_EN) and for voltage window
compliance reporting (FAULT) over the +2.5V to +12V
voltage range.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets; molding compounds/die attach
materials and 100% matte tin plate PLUS ANNEAL - e3 termination
finish, which is 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.
