&lt;p&gt;When Q1 conducts, current is sourced from VIN into ground through the lower half of the primary of the transformer. This creates a negative potential at the lower half of the primary, winding with respect to the primary center tap. In order to maintain the previously established current through Q2 , which has now been opened, the upper half of the primary turns positive with respect to the center tap of the primary. This voltage is now transferred to the secondary of the transformer according to the dot convention and the turns ratio of the transformer. CR1 is now forward biased and CR2 is reverse biased; this in turn causes a current to flow through the upper half of the secondary, passing through CR1 into C charging the capacitor and back into the secondary center tap.&lt;/p&gt;
&lt;p&gt;根据这个说明，请检查以下D2 和C10/11的情况。&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: ISO1042: Do TI have the chip to isolate CAN_H and  CAN_L?</title><link>https://e2echina.ti.com/thread/3889885?ContentTypeID=1</link><pubDate>Mon, 22 Jun 2026 03:09:20 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:0828ad8f-fe13-43ca-a43b-2f22bafd78cc</guid><dc:creator>Lydia</dc:creator><slash:comments>0</slash:comments><comments>https://e2echina.ti.com/thread/3889885?ContentTypeID=1</comments><wfw:commentRss>https://e2echina.ti.com/support/isolation/f/isolation-forum/1080544/iso1042-do-ti-have-the-chip-to-isolate-can_h-and-can_l/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;Hi，&lt;span&gt;we currently do not have a device that isolates CAN bus lines has CANH/CANL lines on both sides.&lt;/span&gt;&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>ISO1042: Do TI have the chip to isolate CAN_H and  CAN_L?</title><link>https://e2echina.ti.com/thread/1080544?ContentTypeID=0</link><pubDate>Sun, 21 Jun 2026 01:37:23 GMT</pubDate><guid isPermaLink="false">91561404-af28-475a-b96b-cb6cbaadd097:5c84b5d3-3a36-43e4-8768-37ea59c409b5</guid><dc:creator>Zhanke Zhao</dc:creator><slash:comments>2</slash:comments><comments>https://e2echina.ti.com/thread/1080544?ContentTypeID=0</comments><wfw:commentRss>https://e2echina.ti.com/support/isolation/f/isolation-forum/1080544/iso1042-do-ti-have-the-chip-to-isolate-can_h-and-can_l/rss?ContentTypeId=0</wfw:commentRss><description>&lt;p&gt;&lt;b&gt;Part Number:&lt;/b&gt; ISO1042&lt;/p&gt;&lt;p&gt;As we know, ISO1042 us a chip to isolate between can_tx can_rx and can_h can_l.&amp;nbsp;&lt;/p&gt;

&lt;p&gt;We have only one can controller,so we only connect one can transceiver at can controller by can_tx and can_rx. Now we need connect two device at can transceiver by can_h and can can_l, and two devices,can transceiver should be isoltated each other.&lt;/p&gt;

&lt;p&gt;1、信号从1V8到3V3。其中一个channel加了3v3上拉10K电阻。&lt;/p&gt;
&lt;p&gt;2、测量B和C点的电压波形发现：1、电压无法拉低--原因已经清楚，由于4.5K和上拉10K分压导致。2、波形中红框部分C点的电压无法拉高，可以看到此时B点的电压是拉高的，但是B点的电压有点毛刺&lt;/p&gt;
&lt;p&gt;疑问点：&lt;/p&gt;
&lt;p&gt;针对下面测量波形，红框标记的位置&lt;/p&gt;
&lt;p&gt;1、为什么B点电压拉高到1V8的时候，C点电压会被拉到1V5，而不是3V3（目前怀疑是跟反相器过流保护相关）&lt;/p&gt;
&lt;p&gt;2、为什么B点的电压出现很多杂波脉冲（怀疑跟内部的one shot有关系）&lt;/p&gt;

&lt;p&gt;8.2.2章节的内容充分解释为什么不建议加上拉电阻，和增加上拉电阻会导致分压，从而导致低压拉不低的情况。&lt;/p&gt;
