3 Description

The ISOS510 radiation-tolerant device is a single-channel, current-driven, analog isolator with transistor output. The device offers significant reliability and performance advantages compared to other current-driven analog isolators, including high bandwidth, low turn-off delay, low power consumption, wider temperature ranges, flat current transfer ratio (CTR), and tight process controls resulting in small part-to-part skew. These performance advantages stay stable across radiation, temperature, and lifetime.

ISOS510 is offered in small a SOIC-4 package with 2.54mm pin pitch, supporting a 3.75kVRMS isolation rating . The high performance and reliability of ISOS510 enables these devices to be used in aerospace & defense applications such as feedback loops in isolated DC/DC modules, satellite propulsion power processing units, spacecraft battery management systems, and more.
