ISL70321SEH, ISL73321SEH

Radiation Hardened Quad Power Supply Sequencers

FN8942

Rev.2.00

Nov 7, 2017

The

ISL70321SEH

and

ISL73321SEH

are radiation

hardened and SEE mitigated power supply sequencers

designed to drive Point-of-Load (POL) regulators with

enable pins. Up to four power supplies can be fully

sequenced by a single device or multiple devices can be

easily cascaded to sequence an unlimited number of

power supplies for dense RF applications.

This power supply sequencer requires only two feedback

resistors per power supply and a single resistor to set the

rising and falling delay. The device features precision

input comparators with an input threshold voltage of

600mV ±1.5% for the highest possible accuracy when

monitoring the power supply voltages.

The ISL70321SEH and ISL73321SEH are offered in an

18 Ld 10mmx12mm CDFP package or die form and are

fully specified across the military ambient temperature

range of -55°C to +125°C.

With minimal external component count, precision

voltage monitoring, and SET mitigation, the

ISL70321SEH and ISL73321SEH are the ideal choice to

control many of today’s highly dense power systems in

high reliability applications.
