Advance Information  
Six-Output Low-Side Switch  
with SPI and Parallel Input  
Control  
33882  
The 33882 is a smart six-output low-side switch able to control  
system loads up to 1.0 A. The six outputs can be controlled via both  
serial peripheral interface (SPI) and parallel input control, making the  
device attractive for fault-tolerant system applications. There are two  
additional 30 mA low-side switches with SPI diagnostic reporting  
(with parallel input control only).  
SIX-OUTPUT LOW-SIDE SWITCH  
The 33882 is designed to interface directly with industry-standard  
microcontrollers via SPI to control both inductive and incandescent  
loads. Outputs are configured as open-drain power MOSFETs  
incorporating internal dynamic clamping and current limiting. The  
device has multiple monitoring and protection features, including low  
standby current, fault status reporting, internal 52 V clamp on each  
output, output-specific diagnostics, and protective shutdown. In  
addition, it has a mode select pin affording a dual means of input  
control.
