... VSSD 8. Functional description 8.1 General The TDA8922C is a two-channel audio power amplifier that uses Class D technology. For each channel, the audio input signal is converted into a digital Pulse Width Modulation (PWM) signal using an analog input stage and a PWM modulator; see the output power transistors, the digital PWM signal is fed to a control and handshake block and to high- and low-side driver circuits ...

Page 6

... Each of the two audio channels contains a PWM modulator, an analog feedback loop and a differential input stage. The TDA8922C also contains circuits common to both channels such as the oscillator, all reference sources, the mode interface and a digital timing manager. The two independent amplifi ...

... How the device reacts to a fault conditions depends on which protection circuit has been activated. 8.3.1 Thermal protection The TDA8922C employes an advanced thermal protection strategy. A TFB function gradually reduces the output power within a defined temperature range. If the temperature continues to rise, OTP is activated to shut down the device completely. ...

... Amplifier is switched off due to OTP. Fig 6. 8.3.2 OverCurrent Protection (OCP) In order to guarantee the robustness of the TDA8922C, the maximum output current delivered at the output stages is limited. OCP is built in for each output power switch. OCP is activated when the current in one of the power transistors exceeds the OCP threshold (I load ...

... C switch-off. C frequency-dependent impedance drops at the speakers. The amplifier will switch on, and remain in Operating mode, once the overcurrent condition has been removed. OCP ensures the TDA8922C amplifier is fully protected against short-circuit conditions while avoiding audio holes. Table 4. Type ...

Page 11

... NXP Semiconductors Start-up will be interrupted If a short-circuit is detected between one of the output terminals and pin VDDP1/VDDP2 or VSSP1/VSSP2. The TDA8922C will wait until the short-circuit to the supply lines has been removed before resuming start-up. The short circuit will not generate large currents because the short-circuit check is carried out before the power stages are enabled. • ...

... Mono BTL operation: the inputs must be connected in anti-parallel. The output of one channel is inverted and the speaker load is connected between the two outputs of the TDA8922C. In practice (because of the OCP threshold) the output power can be boosted to twice the output power that can be achieved with the single-ended confi ...
