ES1030QI

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.
