For my application, I want a short and crisp click similar to the tactile feedback of an automotive touch switch. 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. My code about LRA is as following in lra_demo.c(I only attach part of configing and playing waveform): lra_demo.c The attached oscilloscope waveforms were captured directly across the LRA actuator terminals (positive and negative terminals). 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) So I want to know how to get a short and crisp click and whether my code has something wrong.DRV2605L-Q1https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914745Thu, 06 Aug 2026 23:10:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:83b4be0f-c89d-413a-a177-f598a4ffad90Taylor选择DRV8316的话，在 CSA噪声水平上肯定会有所下降，但官方并没有具体的数据对比https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087604/drv8434a-q1/3914413Thu, 06 Aug 2026 07:46:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:3e5d141d-ed8b-465c-8659-7667f580b1f2Alice您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087604/drv8434a-q1Thu, 06 Aug 2026 07:14:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:46c0dab8-ed34-4507-a101-0d2c901dcd7fLU JIAMINGPart Number: DRV8434A-Q1 Other Parts Discussed in Thread: DRV8434 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。问题出在哪里航天和国防DRV8434DRV8434A-Q1DRV8434AEVMhttps://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914404Thu, 06 Aug 2026 06:11:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:d7f57ae5-8be4-4e44-9a81-139cf3ceb5d4云隆 龚货期长https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914402Thu, 06 Aug 2026 06:07:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:adabc8f0-33ac-4ccd-a6db-dc09a4984389云隆 龚但是很难买到https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914372Wed, 05 Aug 2026 23:38:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:11d85c43-d078-4566-aa32-2067ea695798TaylorDRV8316C（包括DRV8316C-Q1）是可用状态，并非不可用https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087577/tps2549-tps2549/3914370Wed, 05 Aug 2026 23:27:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:352da3c4-b7db-482e-85de-dd6950378c5aTaylor您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914353Wed, 05 Aug 2026 11:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:41c8c211-3c2b-47a7-9040-3299f0219f41云隆 龚从 DRV8316C（包括DRV8316C-Q1）切换到DRV8316（DRV8316-Q1）https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914352Wed, 05 Aug 2026 11:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:46016bb4-fc77-4afa-81d6-128a67858d83云隆 龚从 DRV8316C（包括DRV8316C-Q1）切换到DRV8316（DRV8316-Q1）https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087577/tps2549-tps2549Wed, 05 Aug 2026 10:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:53e56e72-b48a-4d66-9cd0-13a168042e65Lvy JIANGPart Number: TPS2549 你好，在使用tps2549过程中遇到一些问题，需要帮忙解答 我们使用DCP模式，测了一些手机，但是电流都没达到规格书所说的5V，1.5A。 我们仪表是typeC接口 急需专业人员来电解答，可以电话联系13713847065，急！！TPS2549汽车中的 48Vhttps://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914236Wed, 05 Aug 2026 02:17:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:934dc412-f92a-4113-b9b2-b1e0d9d966b8Taylor描述不是很清楚，是从 DRV8316-Q1还是DRV8316C切换到DRV8316？ DRV8316C是增强型CSA规格，而且DRV8316C（包括DRV8316C-Q1）是可用状态，https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-level/3914235Wed, 05 Aug 2026 02:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:d2dfa3c7-12bc-40b4-9357-8aa5b90f4fdbTaylor您好， 已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/motor-drivers/f/motor-drivers-forum/1087519/drv8316-change-drv8316-from-drv8316c-about-csa-noise-levelWed, 05 Aug 2026 02:02:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:b989d5e2-6b00-4cd1-84d1-04ac9ec1e93d云隆 龚Part Number: DRV8316 Due to the unavailability of the DRV8316-Q1, if I switch to the DRV8316, the CSA (Current Sense Amplifier) error doubles.
