... 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 TLE6281G offers an inhibit mode to put the device to sleep and assure low quiescent currents. To deac- tivate the inhibit mode the INH pin has to be set to high. This can be done by connecting this pin to voltages between 3 ...
