你这个现象，应该是触发保护了，无法完成正常的启动。

把HV引脚上接入100V的电压，测量VDD一直只有接近4V的电压，并且电压升高，VDD电压也不变

RE: UCC28730-Q1: UCC28730无法正常启动工作

Wu Kai — Tue, 25 Aug 2026 06:02:35 GMT

我们在调试这个，现在的现象是VDD在21V-7V之间来回充放电，然后VS引脚和DRV引脚就只有一个脉冲，然后VDD电压就从21V开始往下掉。

你这个是个别现象还是普遍现象，是不良分析吗?还是设计咨询。

PSPICE-FOR-TI: PSPICE-FOR-TI: Request to reset device activation - concurrent device access limit reached

Haoran Tang — Fri, 21 Aug 2026 12:59:38 GMT

Part Number: PSPICE-FOR-TI

Tool/software: PSpice for TI

Hello TI support team,

I am encountering the following error when trying to activate PSpice for TI on my new computer:

"You have reached the concurrent device access limit. Too many devices are attempting to connect with the same access key."

My license has already been activated on 3 machines, and some of the old machines are no longer in use (one was replaced / scrapped / had a hardware failure), so I am unable to deactivate them locally.

Could you please help reset / release the existing device activations so that I can activate PSpice for TI on my current machine?

My registered email address: 2328652683qq.com

I can provide the old MAC addresses or any other information needed for verification via private message.

Thank you very much for your assistance.

Best regards,
Kevin
