Configurable Octal Serial Switch

MC33879 Active

The NXP® MC33879 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 MCU for pulse-width modulation applications
  • Incorporates SMARTMOS® technology with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs
  • Controls various inductive, incandescent, or LED loads by directly interfacing with a MCU
  • We recommend the use of the "B" version devices for new designs

Features

Key Features

  • Designed to operate 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 application)
  • Internal reverse battery protection on VPWR
  • Loss of ground or supply will not energize loads or damage IC
  • Maximum 5.0 µA IPWR standby current at 13 V VPWR
  • RDS(ON) of 0.75 Ohm at 25 °C typical
  • Short-circuit detect and current limit with automatic retry
  • Independent over-temperature protection
