10 / 36 page  2001 Dec 11 10 Philips Semiconductors Preliminary specification Controller class-D audio amplifier TDA8929T 8.3.3 START-UP SAFETY TEST During the start-up sequence, when pin MODE is switched from standby to mute, the condition at the output terminals of the power stage are checked. These are the same lines as the feedback inputs of the controller. In the event of a short-circuit of one of the output terminals to VDD or VSS the start-up procedure is interrupted and the system waits for non-shorted outputs. Because the test is done before enabling the power stages, no large currents will flow in the event of a short-circuit. This system protects against short-circuits at both sides of the output filter to both supply lines. When there is a short-circuit from the outputs of the power stage to one of the supply lines, before the demodulation filter, it will also be detected by the start-up safety test. Practical use from this test feature can be found in detection of short-circuits on the printed-circuit board. Remark: this test is only operational prior to or during the start-up sequence, and not during normal operating. 8.4 Differential audio inputs For a high common mode rejection and a maximum flexibility of application, the audio inputs are fully differential. By connecting the inputs anti-parallel the phase of one of the channels is inverted, so that a load can be connected between the two output filters. In this case the system operates as a mono BTL amplifier (see Fig.5). Also in the stereo single-ended configuration it is recommended to connect the two differential inputs in anti-phase. This has advantages for the current handling of the power supply at low signal frequencies. handbook, full pagewidth MGW185 TDA8929T REL1 SW1 EN1 EN2 SW2 OUT1 SGND OUT2 REL2 IN1 + Vi IN1 − IN2 + IN2 − CONTROLLER POWER STAGE Fig.5 Mono BTL application. |
