33879  
33879A  
The 33879 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  
microcontroller for pulse-width modulation (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.

Features  
32-PIN SOICW  
• Designed to operate 5.5 V < VPWR < 26.5 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 Ω at 25 °C typical
