Delivering 75W per channel into 4 Ohm from a 25V supply with THD+N below 0.03%, it provides premium sound quality for car audio systems. The I2S\/TDM digital audio input eliminates the need for external DACs, while I2C-controlled diagnostics detect speaker open\/short circuits and output-to-battery faults. The 40V load dump tolerance ensures robustness on the automotive power bus. The HSSOP-56 PowerPAD package provides efficient thermal dissipation in space-constrained automotive modules.","working_principle":"The TAS6424MQDKQRQ1 uses a bridge-tied-load (BTL) Class-D topology where each channel consists of two N-channel MOSFET half-bridges driven in anti-phase. The digital audio input (I2S or TDM) is processed by an internal DSP that performs interpolation, sigma-delta modulation, and power stage drive. The 2.1 MHz switching frequency can be set above the AM broadcast band to avoid interference with car radios. The I2C diagnostic engine continuously monitors the output pins using AC and DC measurements, detecting open circuits (up to 6 kOhm), short circuits, and output-to-battery\/ground faults without audible pops. DC offset protection disables outputs if a DC voltage exceeding the threshold is detected on any channel, protecting speakers from damage.","pin_description":"\n
