&lt;p data-end="316" data-start="211"&gt;I am using the DRV2605L-Q1 to drive an LRA actuator in RTP mode (Mode = 0x05) with closed-loop operation.&lt;/p&gt;
&lt;p data-end="316" data-start="211"&gt;For my application, I want a &lt;strong data-end="1827" data-start="1802"&gt;short and crisp click&lt;/strong&gt; similar to the tactile feedback of an automotive touch switch.&lt;/p&gt;
&lt;p data-end="585" data-start="318"&gt;The device has completed Auto Calibration successfully, and the calibration results are stored and used during initialization. The LRA can vibrate normally, but I have observed that the vibration intensity during the startup period is noticeably weaker than expected.&lt;br /&gt;&lt;br /&gt;My code about LRA is as following in lra_demo.c(I only attach part of configing and playing waveform):&lt;br /&gt;&lt;a href="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/121/4628.lra_5F00_demo.c" target="_blank" rel="noopener" data-temp-id="lra_demo.c-4037"&gt;lra_demo.c&lt;/a&gt;&amp;nbsp;&lt;/p&gt;
&lt;p data-end="585" data-start="318"&gt;&amp;nbsp;&lt;/p&gt;
&lt;p data-end="585" data-start="318"&gt;The attached oscilloscope waveforms were captured directly across the LRA actuator terminals (positive and negative terminals).&lt;/p&gt;
&lt;p data-end="585" data-start="318"&gt;&lt;img src="https://e2echina.ti.com/cfs-file/__key/communityserver-discussions-components-files/121/4628.5db489dc3f7a546ebf5b18119863822.jpg" alt="5db489dc3f7a546ebf5b18119863822.jpg" width="367" height="275" data-temp-id="5db489dc3f7a546ebf5b18119863822.jpg-223532" /&gt;&lt;/p&gt;
&lt;p data-end="585" data-start="318"&gt;If I extend the vibration duration, the perceived vibration becomes stronger. However, the vibration also becomes less crisp.(I have have tested the mode 0 internel trigger and used library6. But they are all not my expected effects)&lt;br /&gt;&lt;br /&gt;So I want to know how to get a short and crisp click and whether my code has something wrong.&lt;/p&gt;</description></item><item><title>DRV8434A-Q1: 电机无法被驱动</title><link>https://e2echina.ti.com/thread/1087604?ContentTypeID=0</link><pubDate>Thu, 06 Aug 2026 07:14:39 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:46c0dab8-ed34-4507-a101-0d2c901dcd7f</guid><dc:creator>LU JIAMING</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1087604?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087604/drv8434a-q1/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; DRV8434A-Q1&lt;/p&gt;&lt;p&gt;通过上位机软件使用CAN总线向MCU发送电机运动控制指令，MCU通过发送PWM到DRV8434，但是8434无法驱动电机转动。一旦发送指令，nFAULT会被拉低，手册中IFS依次设置电流1A、0.7、0.5、0.4、0.3、0.16A，更改VREF脚分压电阻均不能正常转动，测得DRV8434前端有pwm波，但是没有输出PWM。问题出在哪里&lt;/p&gt;</description></item><item><title>RE: DRV8434A-Q1: 电机无法被驱动</title><link>https://e2echina.ti.com/thread/3914772?ContentTypeID=1</link><pubDate>Fri, 07 Aug 2026 06:01:13 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:e449f6f0-fbcf-41d6-ad0e-8bb7c05af5aa</guid><dc:creator>Alice</dc:creator><slash:comments>0</slash:comments><comments>https://e2echina.ti.com/thread/3914772?ContentTypeID=1</comments><wfw:commentRss>https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087604/drv8434a-q1/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;您好，&amp;nbsp; &amp;nbsp;&lt;/p&gt;

&lt;p&gt;下图的A区域是CP部分，B区域是SH1（pin21开路了），我们想知道是B区域损坏导致的A区域损坏，还是A区域损坏导致B区域损坏。我暂时的理解是，CP短路到地的损坏，应该是整个CP到地的回路造成大规模损坏。&lt;/p&gt;

[quote userid="134433" url="~/support/motor-drivers/f/motor-drivers-forum/1087283/drv3946-q1-pwm/3913496"]如果用自动调节模式一定会发生类似的波形工况吗？[/quote]
&lt;p&gt;如您展示出现周期性不稳定的情况，且干扰到后方，所以建议用相关模式进行修正来测试验证一下，至于是否一定发生这个情况却决于这个情况来源是干扰还是配置问题引起的，通过相关模式可以反向验证这个问题。所以给出相关建议。&lt;/p&gt;
[quote userid="134433" url="~/support/motor-drivers/f/motor-drivers-forum/1087283/drv3946-q1-pwm/3913496"]目前产品要求是20kHz，5V的保持电压(12V供电下)，如果采用固定占空比，我应该如何在不同温度不同供电下(9-16V,-40~85℃)保证线圈不过热，或者斩波后电压波动尽量小？[/quote]
&lt;p&gt;如上述说明这个更改模式一个是为了保证运行另一个是反向验证，如果您有这一部分担心可以在验证上一个问题结果后进行适当匹配。如果是干扰问题可以考虑用外部电路弥补在相关情况来维护您的运行状态。&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
