ISO808A-1 - Galvanic isolated octal high-side power solid state relay

Download the ISO808A-1 datasheet PDF. This datasheet also covers the ISO808A variant, as both devices belong to the same galvanic isolated octal high-side power solid state relay family and are provided as variant models within a single manufacturer datasheet.

General Description

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).

Key Features

  • VCC(AMR) = 45 V.
  • Wide process side op. range VCC = 9.2 to 36 V.
  • RDS(on) = 0.125 Ω per channel (TYP).
  • Fast demagnetization of inductive loads VDEMAG(TYP) = VCC - 54 V.
  • Per channel process side op. current.
  • ISO808A IOUT < 0.7 A.
  • ISO808A-1 IOUT < 1 A.
  • Low process and logic sides supply current.
  • Under-voltage shut down with auto restart and hysteresis.
  • Logic side 5 V and 3.3 V TTL/CMOS and MCU comp.
