Adjustable Quad Sequencer

Features

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.

• Adjustable Delay to Subsequent Enable Signal

• Adjustable Delay to Sequence Auto Start

• Adjustable Distributed Voltage Monitoring

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.

• Undervoltage and Overvoltage Adjustable Delay to Auto

Start Sequence

• I/O Options

ENABLE (ISL8700, ISL8702) and ENABLE# (ISL8701)

SEQ_EN (ISL8702)

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.

• Voltage Compliance Fault Output

• Pb-Free (RoHS Compliant)

Applications

• Power Supply Sequencing

• System Timing Function

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.

2.5V TO 24V (2.5V TO 12V FOR ISL8702)

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.

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.

CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
