Product Overview

This EVALUATION KIT supports the MC33879 device, which is an 8-output hardware-configurable, high side/low side switch with 16-bit serial peripheral interface (SPI) control. Two of the outputs may be controlled directly via microprocessor for PWM applications. The 33879 incorporates SMARTMOS technology, with CMOS logic, bipolar/MOS analog circuitry, and DMOS power MOSFETs. The 33879 controls various inductive, incandescent, or LED loads by directly interfacing with a microcontroller.
  • 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
  • Short-circuit detect and current limit with automatic retry
  • Independent over-temperature protection
  • Short circuit detect and current limit with automatic retry
  • Independent over temperature protection
