Establish power sequencing patterns in small to large multi-rail power systems

06-08-2015 | Mouser Electronics | Power

Altera Enpirion's ES1030QI power rail sequencer is now available from mouser
stock. The low-power small form factor device is ideal for establishing
power sequencing patterns in small to large multi-rail power systems, says
the company.

The ES1030QI 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
device uses power good signals from the regulators to provide feedback of
valid power. The separate fault I/O signals and aggregate PG signals further
enhance the device's utility. Optimized for space-constrained systems, the
sequencer is available in a 2mm x 3mm STQFN package.
