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.TAS2572便携式电子产品https://e2echina.ti.com/support/audio/f/audio-forum/1078828/tas6424e-q1-tas6424-can-not-detect-short-to-power-fault/3884056Thu, 11 Jun 2026 03:10:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:3089da26-e690-4ac1-94ee-2908fbd2768dmingzhi Sunadditional test Preconditions: VBAT = 12.5 V, PVDD = 12.5 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.

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. 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; a short-to-battery fault is indicated on channel 4. Preconditions: VBAT = 14.5 V, PVDD = 14.5 V, channels 1 through 4 are normally connected to 4-ohm loads, and any output pin of channel 4 is shorted to BAT.

Then 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?信息娱乐和仪表组TAS6424E-Q1https://e2echina.ti.com/support/audio/f/audio-forum/1078577/taa5212/3883075Wed, 10 Jun 2026 09:07:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:216026e8-9565-4bbc-a6ce-d981d6187f1fLinks您好， 请点击下面的链接进行申请 https://www.ti.com.cn/drr/opn/PUREPATHCONSOLEhttps://e2echina.ti.com/support/audio/f/audio-forum/1078577/taa5212Wed, 10 Jun 2026 08:50:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:6a20b2f2-e5c7-4d25-8104-3d22e9fe2955Chuanghua LiPart Number: TAA5212 下载调试软件TAA5212PUREPATHCONSOLEhttps://e2echina.ti.com/support/audio/f/audio-forum/1075828/pcm5242rhbevm-demo-48khz-192khz/3883040Wed, 10 Jun 2026 02:33:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:e4b4397a-9f93-4c48-bede-6c324b279210Alice您好， 不支持自适应模式。 (+) PCM5242RHBEVM: PCM5242 采样率在96K/192K的时候，不能调节EQ (HYBRID FLOW 1-7）都不能使用？怎么办？ - 音频论坛 - 音频 - E2E ™ 设计支持https://e2echina.ti.com/support/audio/f/audio-forum/1076864/tas2563-tas2563-mcu/3876688Fri, 05 Jun 2026 08:21:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:21de5743-88e0-403b-9ee8-55e28235732fLinks您好， 请点击下面的链接进行申请 https://www.ti.com/drr/opn/TAS2563-SWhttps://e2echina.ti.com/support/audio/f/audio-forum/1076864/tas2563-tas2563-mcuFri, 05 Jun 2026 08:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:5254c373-dff0-4655-8ea0-3504ce96ddb7ZHIRUIPart Number: TAS2563 TAS2563的MCU驱动代码TAS2563https://e2echina.ti.com/support/audio/f/audio-forum/1076821/pcm5242rhbevm-pcm5242-96k-192k-eq-hybrid-flow-1-7/3876642Fri, 05 Jun 2026 01:46:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:9461d649-d277-4968-894d-05165e1d48b5Daniel您好 首先这是举例，其次这个只表示能完成的数量（处理能力）并不表示固定内容，最后如果您十分在意可以用以下仿真验证一下。 www.ti.com.cn/.../slm008。https://e2echina.ti.com/support/audio/f/audio-forum/1076821/pcm5242rhbevm-pcm5242-96k-192k-eq-hybrid-flow-1-7/3876640Fri, 05 Jun 2026 01:35:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:b41b4c4d-6e3c-41ee-842e-c78b3cc42eefKingsonData sheet的说明不清楚，所以才咨询你们512个指令是指能完成哪些内容？https://e2echina.ti.com/support/audio/f/audio-forum/1076821/pcm5242rhbevm-pcm5242-96k-192k-eq-hybrid-flow-1-7/3876638Fri, 05 Jun 2026 01:19:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:ddd0b811-fa86-4ed3-988d-46f67827c9b2Daniel您好 请您参考datasheet说明，说明明确表示处理能力有限，望您见谅。https://e2echina.ti.com/support/audio/f/audio-forum/1076844/opa1688-opa1688idrg/3876637Fri, 05 Jun 2026 01:14:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:57ff9524-27fa-438f-b69e-86ab1f84002dFRANK1散热焊盘连到V-，与V-电平一致。https://e2echina.ti.com/support/audio/f/audio-forum/1076821/pcm5242rhbevm-pcm5242-96k-192k-eq-hybrid-flow-1-7/3876635Fri, 05 Jun 2026 01:11:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:ffc186c8-1388-4393-adb8-2e94ffb29a49Kingson512个指令是只能处理什么，一个QIUD 都不能调整吗？只能是bypass？https://e2echina.ti.com/support/audio/f/audio-forum/1076845/opa1688-opa1688idrg/3876634Fri, 05 Jun 2026 01:10:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:757f5b61-f03c-4692-b9e8-1e276e577e4bEirwen散热焊盘应连接至V-，以使其电位与芯片基板保持一致。https://e2echina.ti.com/support/audio/f/audio-forum/1076761/tas2120-tas2120-pvdd-adc/3876631Fri, 05 Jun 2026 00:42:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:75e3fc2d-38c9-4fae-a971-1f7e91ba9c9bEirwen内部处理算法会在需要时自动启用升压功能。具体可以参考数据表的.4.4 Internal Boost， 也可能是软硬件的配置问题。 第二个问题的几个寄存器，请问是在哪个资料中出现的？https://e2echina.ti.com/support/audio/f/audio-forum/1076845/opa1688-opa1688idrg/3876630Fri, 05 Jun 2026 00:34:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:f33e34c1-efa1-4e2d-8d1c-619b0b0dcecaFRANK1感谢您对TI产品的关注！ 关于你的咨询，我们正在确认您的问题，感谢您的耐心等待。https://e2echina.ti.com/support/audio/f/audio-forum/1076845/opa1688-opa1688idrgFri, 05 Jun 2026 00:33:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:0e100826-e95e-4dbf-8b5d-a4e1f8fe74ceXuesen SangPart Number: OPA1688 最近计划用OPA1688IDRG设计产品，但其封装底部散热焊盘接没给出电气属性，我们是应该悬空、接V-、接V+或者是接GND ？？？OPA1688https://e2echina.ti.com/support/audio/f/audio-forum/1076844/opa1688-opa1688idrg/3876629Fri, 05 Jun 2026 00:33:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:3e539c2c-3ccd-45ae-b66d-9b1cfa7a8818FRANK1感谢您对TI产品的关注！ 关于你的咨询，我们正在确认您的问题，感谢您的耐心等待。https://e2echina.ti.com/support/audio/f/audio-forum/1076844/opa1688-opa1688idrgFri, 05 Jun 2026 00:31:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:39e6ef27-0dfe-4d00-9906-9854b6a06b87Xuesen SangPart Number: OPA1688 最近计划用OPA1688IDRG设计产品，但其封装底部散热焊盘接没给出电气属性，我们是应该悬空、接V-、接V+或者是接GND ？？？OPA1688
