The MAX13300/MAX13302 combine four high-efficiency Class D amplifiers with integrated diagnostic hardware for reliable automotive audio systems. The MAX13300/ MAX13302 deliver up to 50W at 10% THD+N per channel into 2Ω when operating from a 14.4V supply. The internal diagnostics evaluate each channel’s output impedance to check for shorts across the outputs, to the battery, or to ground. The I2C interface allows the system to query critical device parameters such as device temperature and output clipping. The devices are programmable to four different I2C addresses. The audio amplifiers feature single-ended analog inputs with a common negative input. Three gain settings are internally adjustable through the I2C interface to 13dB, 21.6dB, and 26dB. The Class D amplifier has 10 programmable switching frequencies between 300kHz and 750kHz. The BTL outputs are protected against short circuits and thermal overload. The outputs can be configured as a 2-, 3-, or 4-channel amplifier. All the devices provide 50V load-dump protection, and are offered in the thermally enhanced, 48-pin TSSOP-EPR package operating over the -40°C to +125°C temperature range.
