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.

The voltage divider networks accross the 4 MOSFETs (resistors RSCDxx) allow to increase the current limit threshold for Short Circuit protection. The RSCDLx resistors also provide a charge path for the bootstrap capacitors. If RSCDLx resistors are not used in the application, a 12k Ohm resistor should be introduced between SH1 to GND and SH2 to GND.
