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