Power Sequencing Controllers
The Intersil ISL6123, ISL6124, ISL6125, ISL6126, ISL6127,
ISL6128 and ISL6130 are integrated four 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 SYSRESET# pins of cascaded IC's. The
ISL6125
uses four open-drain outputs to control the on/off sequencing
of four supplies, while 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 IC's
can be biased from any supply 5V down to 1.5V. Individual
product descriptions follow.
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
and
ISL6130
have a low power standby mode when 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 majority, for both the
ISL6126
and
ISL6130
each of the four channels operates independently so that the
various GATEs will turn 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 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.
