Application Information
The TLE6251DS has two operation modes, the normal and the standby mode. These modes can
be controlled with the STB pin (see
up, so if there is no signal applied to STB or STB = HIGH, the standby mode is activated. To
transfer the TLE6251DS into the normal mode, STB has to be switched to LOW.
