Preliminary Information  
33879  
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. 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 overtemperature protection.
