FN6381.0

Adjustable Quad Sequencer

Features

The ISL8700A, ISL8701A, ISL8702A, ISL8703A, ISL8704A,

ISL8705A 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 sub-systems

require input power sequencing for proper functionality at

initial power up and the ISL870XA provides this function

while monitoring the distributed voltage for over and

undervoltage compliance.

• Under and Overvoltage Adjustable Delay to Auto Start

Sequence

• I/O Options

ENABLE (ISL8700A, ISL8702A, ISL8704A) and

ENABLE# (ISL8701A, ISL8703A, ISL8705A)

SEQ_EN (ISL8702A, ISL8703A) and

SEQ_EN# (ISL8704A, ISL8705A)

These ICs operate over the +3.3V to +24V nominal voltage

range. All 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 Plus Anneal Available (RoHS Compliant)

Additionally, the ISL8702A, ISL8703A, ISL8704A and

ISL8705A provide I/O for sequencing on and off operation

(SEQ_EN) and for voltage window compliance reporting

(FAULT) over the +3.3V to +24V nominal voltage range.

Applications

• Power Supply Sequencing

• System Timing Function

Easily daisy chained for more than 4 sequenced signals.

Altogether, the ISL870XA provides these adjustable features

with a minimum of external BOM. See Figure 1 for typical

implementation.

1. 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.
