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.
