Radiation Hardened Passive-Input Digital Isolator Evaluation Board

The ISL71610SLHMEV1Z evaluation board provides a quick and easy method for evaluating the ISL71610SLHM Giant Magnetoresistive (GMR) digital isolator. This IC is a radiation hardened digital isolator designed for isolated power supply designs and isolated serial communications interfaces, such as CAN, SPI, RS-422, and RS-485 applications.

The ISL71610SLHM is a passive input, active output GMR digital isolator that requires a 3V to 5.5V supply to power its CMOS output. This GMR isolator can replace some of the available optocouplers currently used in space applications. Whereas optocoupler lines are susceptible to Total Ionizing Dose (TID) radiation that causes the optics to become cloudy and therefore compromising the signal, the GMR inductive structure used in the ISL71610SLHM is inherently immune to radiation effects.
