ISO808A

Galvanic isolated octal high-side power solid state relay with SPI interface for high inductive loads

ECCN USEAR99
ECCN EUNEC
Packing TypeTube
RoHs compliantEcopack2
GradeIndustrial
Package NamePowerSO 36

The ISO808A, ISO808A-1, are galvanic isolated 8-channel drivers featuring a low supply current. Each driver contains 2 independent galvanic isolated voltage domains (VCC and VDD for the Process and Control Logic stages, respectively). The ICs are intended for driving any kind of load with one side...
