NXP single digitalloop Class-D amplifiers TDF853x Class-D amplifiers for an A+ audio experience Equipped with a single digital-feedback loop, these ultra-performance Class-D amplifiers reduce system cost in automotive applications while delivering unparalleled sound quality. KEY FEATURES } Three, four, or five 2 or 4 load Class-D BTL channels } Interleaved power stages (optional) for improved EMC and reduced output-filter cost/complexity } Two BTL channels can combine to drive 1 } Feedback after low-pass filter for lower BOM cost and better audio quality TARGET APPLICATIONS } Automotive head-unit radio } Automotive sound systems } Operation voltage from 5.5 V to 18 V (optional 25 or 45) } Automotive-engine sound design } Digital input in TDM/I�S format to ensure easy board layout } Line-driver mode to drive an external amplifier via direct loudspeaker cable } Quality in accordance with AEC-Q100 } Diagnostic � Startup diagnostic for AC and DC coupled loads � Supply voltage feedback with 8-bit resolution � Selectable clip detection The NXP TDF853x family is a series of ultra-efficient Class-D amplifiers that create a seamless audio experience in vehicles that support 5.5 V stop- start requirements. Ideally suited for use in active noise-cancellation systems, these amplifiers also fit head units and sound systems, and can be used to generate ambient and/or engine sounds in electric vehicles. The output power per channel varies with the supply voltage. The devices support up to 18 or 25 V, with 45 V to drive the loudspeaker. � Selectable diagnostic information on DIAG pins � IEEE 1194.1-compliant, board-level boundary scan � DC output offset diagnostics The TDF8531 has three channels, the TDF8532 has four channels, and the TDF8534 has five channels. The TDF8536 has four 45 V channels. } Protection - Independent output current per channel with selectable thresholds � Load dump protection (50 V) � Over- and undervoltage protection � Thermal fold-back and thermal protection HLQFP100 PACKAGE TDF853X CLASS-D AMPLIFIER REFERENCE DESIGN TDF853X BLOCK DIAGRAM 53x BLOCK DIAGRAM MOD1 MOD2 MOD3 GPIO1 DIAG1 DIAG2 DIAG3 ENABLE VDDA VDDE VDDP VDDD ADS1 ADS2 ADS3 SCL SDA MUTE_N SDI1 SDI2 SDI3 FS SCLK SYNC Microprocessor Diagnostic I2C Protections Supply Monitor Temp Monitor Supplies and References Charge Pump I2S/TDM Input Channel 1 of 5 Digital Loop Filter PWM Control PLL JTAG LLADC CPCP CPCM CP CP_DRV VDDP_DRV VDDP1 OUT1P1 OUT1P2 OUT1M1 OUT1M2 VSSP1 FB1P FB1M TDO TDI TMS TCK TRST_N VSSP VSSA VSSD HW SELECTION GUIDE Type Channel TDF8531HH 3 TDF8532HH 4 TDF8532BHH 4 TDF8534HH 5 TDF8534BHH 5 TDF8536HH 4 Supply 5.5 V � 25 V 5.5 V � 25 V 5.5 V � 18 V 5.5 V � 25 V 5.5 V � 18 V 5.5 V � 45 V Max output power 3 x 80 W 4 x 80 W 4x 70 W 5 x 80 W 5x 70 W 4 x 140 W THD+N / Noise Parallel Mode 0.005 % 26 �V Yes 0.02 % 26 �V Yes 0.005 % 42 �V � 0.005 % 26 �V Yes 0.02 % 42 �V � 0.005 % 48 �V Yes Idle Power Dissipation 2.1 W 2.8 W 2.8 W 3.5 W 3.5 W 3.0W Interleaved Mode Key Code Key Code � Key Code � Included www.nxp.com NXP and the NXP logo are trademarks of NXP B.V.
