ES1022SI Adjustable Quad Sequencer

ES1022SI

Datasheet

The ES1022SI IC provides four delay adjustable

sequenced outputs while monitoring an input voltage all

with a minimum of external components.

Features

• Adjustable Delay to Subsequent EN 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 ES1022SI

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: EN and SEQ_EN

This IC operates over the +3.3V to +24V nominal voltage

range. It has 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 EN output signal via external

resistors.

• Voltage Compliance Fault Output

• Pb-Free Plus Anneal Available (RoHS Compliant)

Applications

• Power Supply Sequencing

• System Timing Function

Additionally, the ES1022SI provides 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.

Easily daisy chained for more than 4 sequenced signals.

Altogether, the ES1022SI provides these adjustable

features with a minimum of external BOM. See Figure 1

for typical implementation.
