ISO808A-1 Datasheet Galvanic Isolated Octal High-side Power Solid State Relay

Manufacturer: STMicroelectronics

Overview: ISO808A, ISO808A-1 Datasheet Galvanic isolated octal high-side power solid state relay with SPI interface for high inductive loads Product status link ISO808A ISO808A-1 Product.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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).

The ICs are intended for driving any kind of load with one side connected to ground.

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.
