Features
Application
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.

... Description of Inhibit functionality In automotive applications which are permanently connected to the battery line very im- portant to reduce the current consumption of the single devices. Therefore the TLE6284G offers an inhibit mode to put the device to sleep and assure very low quiescent currents. To deactivate the inhibit mode the INH pin has to be set to high. This can be done by connect- ing this pin to voltages between 3 ...
