The TDF8530, one of the latest additions to NXP’s portfolio, is an ultra-efficient, quad-channel Class-D audio amplifier that supports the 6 V requirement for start-stop vehicles. It enables a rich, seamless audio experience in hybrid electric vehicles, micro-hybrids, mild hybrids, and other energy-saving vehicles that use start-stop systems. The TDF8530 is optimized for use in the head-unit radio and in sound-system platforms. It also supports new applications, such as ambient sound systems, which generate engine sounds in electric vehicles, and active noise-cancellation systems. The TDF8530 is an ultra-efficient device, generating 70 W per channel at the maximum supply voltage of 24 V. It delivers optimal sound under maximum power conditions, offers outstanding EMC performance, and uses a thermal fold-back, integrated in hardware, to protect the device from overheating. A full range of diagnostics and protections ensure full robustness in the harsh automotive environment. Controlled by the I2C bus, the diagnostics cover familiar functions such as speaker protection, clip detection, and AC load tweeter detection, and also include unique features for start-up functions.
