Enpirion® Power Datasheet
ES1030QI Power Rail Sequencer
Features
Four enable outputs
Four power good feedback signals
Can be chained with additional devices to achieve
>16 sequenced rails
Precise, adjustable qualification time for sequenced
supplies (33us to 8.04ms)
Aggregate PG signal for the logical AND of the
individual PG signals
Wide 1.8 V to 5.0 V nominal voltage range
Low power consumption
Pb-free/ RoHS compliant
Halogen-free
STQFN-20 package
Description
The ES1030QI Power Rail Sequencer is a low-power
and small-form factor device ideal for establishing the
power sequencing pattern in small to large multi-rail
power systems (please refer to Figure 6). The part
provides nested sequencing of four outputs per
device, with the ability to attach additional devices in
a sequencing chain for at least 16 outputs. A simple
resistor divider establishes a precise qualification time
window by determining if each power rail is valid at
the correct time. The part uses power good signals
from the regulators to provide feedback of valid
power. Separate fault I/O signals and aggregate PG
signals further enhance the utility of this device. The
sequencer is available in a 2mm x 3mm STQFN
package, optimal for use in dense systems.
