Application  
Dedicated for DC-brush high current motor bridges in PWM control mode for 12, 24 and 42V powernet applica-  
tions.  
The input structure allows an easy control of a DC-brush motor  
General Description  
H-bridge driver IC for MOSFET power stages with multiple protection functions.  
The TLE6184G is very similar to the TLE6281G. The major difference is that the Short Circuit protection level of  
the TLE6284G can be adjusted by external resistors or even disabled. The pin outs are different as well.
