By Intel® FPGAs 111
Intel®'s ES1030QI power rail sequencer is a low-power and small-form device ideal for establishing the power sequencing pattern in small to large multi-rail power systems. 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 SoC is available in a 2 mm x 3 mm STQFN package, optimal for use in dense systems.
