The Intersil ISL6123, ISL6124, ISL6125, ISL6126, ISL6127,
ISL6128 and ISL6130 are integrated 4-channel
controlled-on/controlled-off power-supply sequencers with
supply monitoring, fault protection and a “sequence completed”
signal (RESET). For larger systems, more than four supplies can
be sequenced by simply connecting a wire between the
SYSRESET pins of cascaded ICs. The ISL6125 uses four active
open-drain outputs to control the on/off sequencing of four
supplies. The other sequencers use a patented, micropower 7x
charge pump to drive four external low-cost NFET switch gates
above the supply rail by 5.3V. These ICs can be biased from 5V
down to 1.5V by any supply.
The 4-channel ISL6123 (ENABLE input), ISL6124 (ENABLE
input) and ISL6125 offer the designer 4-rail control when all
four rails must be in minimal compliance before turn-on and
during operation. The ISL6123 and ISL6130 have a low-power
standby mode when disabled, which is suitable for
battery-powered applications.
The ISL6125 operates like the ISL6124, but instead of
charge-pump-driven gate drive outputs, it has open-drain logic
outputs for direct interface to other circuitry.
In contrast, for the ISL6126 and ISL6130, each of the four
channels operates independently. Each GATE turns on once its
individually associated input voltage requirements are met.
The ISL6127 is a pre-programmed A-B-C-D turn-on and D-C-B-A
turn-off sequenced IC. Once all inputs are in compliance and

ENABLE is asserted, sequencing begins. Each subsequent GATE
turns on after the previous one turns on.
The ISL6128 has two groups of two channels, each with its
independent I/O. It is ideal for voltage sequencing into
redundant capability loads. All four inputs must be satisfied
before turn-on, but a single group fault is ignored by the other
group.
External resistors provide flexible voltage threshold
programming of monitored rail voltages. Delay and
sequencing are provided by external capacitors for ramp-up
and ramp-down.
Additional I/O is provided for indicating and driving the RESET
