Freescale Semiconductor Advance Information Document Number: MC33879 Rev 6.0, 6/2007 Configurable Octal Serial Switch with Open Load Detect Current Disable The 33879 device is an 8-output hardware-configurable, high-side / low-side switch with 16-bit serial input 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.
