MC33879 - Configurable octal serial switch

General Description

The 33879 device is an 8-output hardware configurable, high-side/low-side switch with 16-bit serial input control using the Serial Peripheral Interface (SPI).

Two of the outputs may be controlled directly via a microcontroller for pulse-width modulation (PWM) applications.

Key Features

  • Designed to operate at 5.5 V < VPWR < 27.5 V.
  • 16-bit SPI for control and fault reporting, 3.3 V / 5.0 V compatible.
  • Outputs are current limited (0.6 A to 1.2 A) to drive incandescent lamps.
  • Output voltage clamp, + 45 V (low side) and.
  • 20 V (high side) during inductive switching.
  • On/Off control of open load detect current (LED.
