MOTOROLA  
SEMICONDUCTOR TECHNICAL DATA  
Preliminary Information  
33892  
Quad Intelligent High-Side Switch  
(Dual 10 mand Dual 35 m)  
The 33892 is one in a family of devices designed for low-voltage automotive  
and industrial lighting and motor control applications. Its four low RDS(ON)  
QUAD INTELLIGENT  
HIGH-SIDE SWITCH  
MOSFETs (two 10 m, two 35 m) can control the high sides of four separate  
resistive or inductive loads or serve as high-side switches for a pair of DC  
motors.  
Programming, control, and diagnostics are accomplished using a 16-bit SPI  
interface. Additionally, each output has its own parallel input for PWM control  
if desired. The 33892 allows the user to program via the SPI the fault current  
trip levels and duration of acceptable lamp inrush or motor stall intervals. Such  
programmability allows tight control of fault currents and can protect wiring  
harnesses and circuit boards as well as loads.  
The 33892 is packaged in a power-enhanced 10x 10 nonleaded Power  
QFN package with exposed tabs.
