TAS2572: How to add the IV-sense protection algorithm for TAS2572 on Qualcomm platform?

Wang Holy — Thu, 11 Jun 2026 07:54:21 GMT

Part Number: TAS2572

The product uses a Qualcomm platform, and the TAS2572 driver selected is the RCA driver, which runs on the AP side (ARM). According to the previous support engineer’s explanation, this driver does not include speaker protection algorithms. The customer now requests the addition of the IV-sense protection algorithm. Should this protection algorithm run on the ADSP side or the AP side? Please help provide the relevant algorithm and porting documentation.

TAS6424E-Q1: TAS6424 can not detect "short to power" fault

mingzhi Sun — Thu, 11 Jun 2026 03:01:36 GMT

Part Number: TAS6424E-Q1

While testing the fault diagnostics function of the TAS6424, I encountered an issue where a short-to-battery fault cannot be detected. The specific test conditions are as follows:

Preconditions: VBAT = 12.5 V, PVDD = 24.5 V, channels 1 through 4 are normally connected to 4-ohm loads.
Test procedure: After power-up, switch all channels to Play mode and continuously read registers 0x0C and 0x0D; no fault is indicated. Then short any output pin of channel 4 to BAT and continuously read registers 0x0C and 0x0D; no fault is indicated.
Preconditions: VBAT = 12.5 V, PVDD = 24.5 V, channels 1 through 4 are normally connected to 4-ohm loads, and any output pin of channel 4 is shorted to BAT.
Test procedure: After power-up, switch all channels to Play mode and continuously read registers 0x0C and 0x0D; a short-to-battery fault is indicated on channel 4. Then remove the shorting wire from channel 4 and continuously read registers 0x0C and 0x0D; no fault is indicated. Then reconnect the shorting wire to channel 4 and continuously read registers 0x0C and 0x0D; no fault is indicated.
Preconditions: VBAT = 14.5 V, PVDD = 24.5 V, channels 1 through 4 are normally connected to 4-ohm loads, and any output pin of channel 4 is shorted to BAT.

Then remove the shorting wire from channel 4 and continuously read registers 0x0C and 0x0D; no fault is indicated. Then reconnect the shorting wire to channel 4 and continuously read registers 0x0C and 0x0D; a short-to-battery fault is indicated on channel 4.

Then reconnect the shorting wire to channel 4 and continuously read registers 0x0C and 0x0D; a short-to-battery fault is indicated on channel 4.

My question is: why does the short-to-battery fault detection vary with different VBAT voltages?

TPA6211A1: 单端输入单端输出

user6235567 — Tue, 26 May 2026 09:39:32 GMT

Part Number: TPA6211A1
Other Parts Discussed in Thread: INA826

我的输入是通过INA826AIDR（该芯片±5V供电）先放大约30倍，然后再单端输入给到TPA6211A1，由于我的输出是接到耳机，单端应用。我直接将TPA6211A1的第8脚也就是Vo-接地（该芯片3.3V供电），Vo+接到耳机。现在的情况放大30倍时，电路板很烫，±5V电源会周期性拉垮。如果我断开TPA6211A1的Vo-与GND的连接，就不会发烫，±5V电压也正常，有如下疑问。

1）TPA6211A1是否支持单端输出？

2）单端输出时Vo－直接接地是否正确？

TAC5212: TAC5212 芯片配置问题咨询

chen hu — Wed, 20 May 2026 10:58:44 GMT

Part Number: TAC5212

这是我的寄存器配置相关值，我打算使用24MHz的外部晶振通过GPIO1输入CCLK时钟，采样频率设置为32k,BCLK/FS =64，BCLK=2.048MHz,按照如图所示配置进行调试，可得几个状态寄存器的值如下，

，

逻辑分析仪抓的数据如图

现在我有几个疑惑，

1、为什么CLK_DET_STS2寄存器值为0x40,最高Bit7-6位手册是保留位，不应该有值，该值好像跟我写入的BCLK/FS=64的值强相关；另外，STS2和STS3的值按照芯片内部自动时钟分配，理论应该为24M/32k=750的值，结果读出来没有值，我感到有些疑惑，该值按照我的理解应该被显示在寄存器中；

2、AVDD_IOVDD_STS寄存器中，AVDD和IOVDD的状态标志寄存器应该为3.3V吧，也就是寄存器值应该为0xC0，电压我用示波器测过，电压均为3.46V左右，结果是0x00；

3、按照其他状态寄存器的值，PLL已经被启用，且已经处在工作模式，我觉得是正常的，不然逻辑分析仪上也不会抓不到时钟，但是测出来的时钟值和理论值差距较大，时钟值甚至为2.088M，与2.048M相差甚远，这种通过芯片分出来的值是正常的吗？还是说我的寄存器配置还是有问题，

Part Number: TPA3116D2

看到规格书关于这个单端输入AC地的描述我有些困惑，这个隔直电容应该靠近SOC端放置还是靠近功放端放置，如果是靠近SOC端放置，经过搁置电容后INP和INN需要走很长一段线直连到功放的INN和INP引脚，INN和INP是理论上是高阻抗敏感线，跟DCDC的FB一样应该不能走很长容易引入干扰；如果隔直电容是跟DEMO板一样放置在靠近功放侧，是否需要从SOC端拉一对伪差分线L和主控端GND到功放，从主控出发的GND不与主板上的其它部分地打孔连接，但这样有人说从主控端拉一根地线到功放端也容易被干扰，不及在功放端单点接地处理，烦请帮忙理清一下思路，我目前就是困惑这个，谢谢
