Power Sequencing Controllers
The Intersil ISL6123, ISL6124, ISL6125, ISL6126, ISL6127,
ISL6128 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 4 supplies can be sequenced
by simply connecting a wire between SYSRESET# pins of
cascaded IC's. The ISL6125 uses 4 open-drain outputs to
control the 4 power supplies, and the other sequencers use
a patented, micropower 7X chargepump to drive 4 external
low-cost NFET switch gates above the supply rail by 5.3V.
These IC's can be biased from any supply 5V down to 1.5V.
Individual product descriptions are below.
The four channel
ISL6123
(ENABLE input),
ISL6124
(ENABLE# input) and
ISL6125
ICs offer the designer 4 rail
control when it is required that all four rails are in minimal
compliance prior to turn on and that compliance must be
maintained during operation. The
ISL6123
has a low power
standby mode when it is disabled, 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 to the ISL6123 and ISL6124, with the
ISL6126
,
each of the four channels operates independently so that the
various rails will turn on once its individual input voltage
requirements are met.
The
ISL6127
is a preprogrammed 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 the sequencing starts and each
subsequent GATE will turn-on after the previous one
completes turning-on.
The
ISL6128
has two groups of two channels each with its
independent I/O and is ideal for voltage sequencing into
redundant capability loads as all four inputs need to be
satisfied prior to 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 both
ramp up and ramp down.
Additional I/O is provided indicating and driving RESET state
in various configurations.
For volume applications, other programmable options and
features can be had. Contact the factory with your needs.

Evaluation Platform
NOTE: 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.
