33879  
33879A  
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. The circuit’s innovative monitoring  
and protection features include very low standby currents, cascade  
fault reporting, internal +45 V clamp voltage for low-side configuration,  
-20 V high side configuration, output specific diagnostics, and  
independent over-temperature protection.
