DATASHEET ISL70321SEH, ISL73321SEH Radiation Hardened Quad Power Supply Sequencers FN8942 Rev.3.0 Jul 30, 2021 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 requir
ISL73321SEH 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 tempe
