&lt;p&gt;电机相间直流电阻实测为 5.6&amp;Omega;。&lt;br&gt;&lt;strong&gt;我的疑问&lt;/strong&gt;：&lt;/p&gt;
&lt;/li&gt;
&lt;li&gt;
&lt;p&gt;针对 5.6&amp;Omega; 的高阻值电机，DRV8316 的电流环 PI 参数是否需要进行特殊调整？是否有推荐的调参步骤？&lt;/p&gt;

&lt;p&gt;我查看了手册和DRV8706S-Q1 EVM开发板设计，没有找到关于该芯片米勒钳位引脚相关描述&lt;/p&gt;
&lt;p&gt;我是否应该考虑米勒钳位相关的事情呢？&lt;/p&gt;
&lt;p&gt;我已经在设计中添加了双向钳位二极管和稳压二极管。&lt;/p&gt;
&lt;p&gt;稳压二极管是在栅极出现伏电压时候用于Vgs钳位在-0.5V左右，这或许不能替代有源米勒钳位或者无源米勒钳位。&lt;/p&gt;

&lt;div&gt;用的DSP芯片TMS320F28069读取片内温度传感器信息。&lt;/div&gt;
&lt;div&gt;参考官方库及detasheet上给出的参考偏差和斜率，两者不一样，并且官方库中没有给出对应地址。&lt;/div&gt;
&lt;div&gt;datasheet具体信息如下：&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;For F2806x:&lt;/div&gt;
&lt;div&gt;&amp;bull; 0x3D7E82 - Slope (&amp;deg;C / LSB, fixed-point Q15 format)&lt;/div&gt;
&lt;div&gt;&amp;bull; 0x3D7E85 - Offset (0 &amp;deg;C LSB value)&lt;/div&gt;
&lt;div&gt;
&lt;div&gt;官方库中没有0x3D7E82和0x3D7E85这两个的宏定义。&lt;/div&gt;
&lt;div&gt;请问没有这两个宏定义地址的情况下，采集到的数据如何转化成具体的温度值呢？&lt;/div&gt;
&lt;div&gt;附代码部分：&lt;/div&gt;
&lt;div&gt;pAdcData-&amp;gt;NTCTemp = ADC_readResult(obj-&amp;gt;adcHandle, ADC_ResultNumber_0); &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; //读取片上温度传感器温度&lt;br&gt;
&lt;p&gt;搜索网上信息，偏移固定为1750，斜率固定为0.18，室温条件下测量出的Temp是57度，仍然不对。&lt;/p&gt;
&lt;p&gt;void Temp_test(FUNC_CODE *handle)&lt;br&gt;{&lt;/p&gt;
&lt;p&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;//Temp = (gAdcData.NTCTemp - getRefTempOffset()) *(int32_t)getOsc1FineTrimSlope(); &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; //读取片上温度传感器温度转换成摄氏度&lt;br&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;Temp = (gAdcData.NTCTemp - 1750) * (0.18); &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp; //读取片上温度传感器温度转换成摄氏度&lt;br&gt;&amp;nbsp; &amp;nbsp; &amp;nbsp; &amp;nbsp;handle-&amp;gt;F3027 = Temp;&lt;br&gt;}&lt;/p&gt;
问题：&lt;/div&gt;
&lt;div&gt;1，具体偏移和斜率应该是什么呢？&lt;/div&gt;
&lt;div&gt;2，采集和计算方法有问题吗？&lt;/div&gt;
&lt;div&gt;请帮忙明确一下，谢谢。&lt;/div&gt;

&lt;p&gt;整体设计架构：驱动板（六路GaN）--&amp;gt;排针--&amp;gt;控制板（隔离芯片+MCU）&lt;/p&gt;
&lt;p&gt;1、低压测试：驱动板功低压48V开环测试电机可以正常运行（程序屏蔽了FAULT信号的输入），FAULT信号一直会叠加干扰信号，将排针上的FAULT信号断开直接测试芯片引脚的FAULT信号已经叠加了干扰信号（干扰信号毛刺测试为控制信号的20KHz）。20KHz的控制信号隔离输出侧无异常。&lt;/p&gt;
&lt;div&gt;2、高压测试：DC300V开环测试电机GaN芯片损坏，损坏原因可能是瞬时的直通造成的炸机，原因目前没有分析出来。测试死区时间是600nS。准备先50%的PWM测试高压信号波形是否正常。&lt;/div&gt;

&lt;p&gt;基于以上需求，我们设计DRV81008时，在芯片GND(pin5/8/17)和样机全局地之间加了一个二级管，防止以上实验时，电流通过体二极管回流。&lt;/p&gt;
&lt;p&gt;设计前，我们测试了芯片GND和EPAD不导通，故只把芯片GND和全局地之间加了二极管，EPAD和全局地直连。&lt;/p&gt;
&lt;p&gt;样机实测时发现，样机输入+接12V,样机输入-悬空，OUT1接地，结果系统启动了。断电后发现芯片GND和EPAD阻抗变为20&amp;Omega;左右，这和实验前的阻抗完全不一样了。实验导致EPAD和芯片GND近乎短路，这是什么原因导致的？EPAD内部电路是咋样的？&lt;/p&gt;
&lt;p&gt;我们同步做了一个尝试，EPAD和全局地断开，重复上面实验，样机不启动。&lt;/p&gt;

&lt;p&gt;目前使用DRV8353RS遇到一個問題：&lt;/p&gt;
&lt;p&gt;1. 依據DRV8353的Datasheet，過電流保護是偵測外部Shunt Resistor的電壓，針對電壓後並沒有將電壓透過內部放大器放大，例如&lt;/p&gt;
&lt;p&gt;Shunt Resistor　0.5mohm&lt;/p&gt;
&lt;p&gt;輸入電流: 50A&lt;/p&gt;
&lt;p&gt;VSENSE = 50A* 0.5m ohm =25mV&lt;/p&gt;
&lt;p&gt;SPI設定中SEN_LVL可以選擇感測過電流的電壓0.25V. 0.5V. 0.75V與1V，這樣我的輸入電流要很大，DRV8353才能夠進入硬體過電流保護，這樣的認知對嗎？&lt;/p&gt;
&lt;p&gt;如果對的話，DRV8353的硬體保護不就失效了嗎？&lt;/p&gt;

&lt;p&gt;开发板：LP-MSPM0G3507&lt;/p&gt;
&lt;p&gt;驱动板：DRV8316REVM&amp;nbsp;&lt;/p&gt;
&lt;p&gt;&amp;nbsp;&lt;/p&gt;
&lt;p&gt;使用 sdk 中的 &amp;nbsp;MSPM0 Universal FOC 例程驱动电机，开环闭环均可转动，但是每间隔 2.4s 电机会跳动一下，通过 Ozone 打印了 Duty 值，发现跳动时 duty 值也会发生畸变，请问这可能是是什么原因。&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;只在开环运行时也会出现这个情况。&lt;/strong&gt;&lt;/p&gt;
