MAX13487E 发送状态下A、B间电平不符合正常逻辑 0
Not Answered

你好，使用贵司MAX13487E，原理图如图，切换到对外发送信号，示波器沟取信号如图，CH1:A-B,CH2：A-GND，CH3:B-GND 其中A对B信号，无法呈现高电平，仅出现高尖峰，但是用485工具能正常读取到数据，看了群组里类似的提问与回答，还是有疑问，如果这是属于正常现象，希望给个官方详细解释。

I'm using the MAX31855 to measure temperature, and when close to the transformer of a switching power supply, a serious temperature error occurs, and I'd like to know how to avoid this interference caused.

您好！在使用贵司的MAX31856MUD+T 芯片测量加热丝温度时，使用工况需要K型热电偶与加热丝贴合使用，加热丝的测温点与加热丝是接触的，芯片会报OVUV的错误无法正常读取温度，这种情况该怎么处理？或者有没有更适合这种工况使用的芯片推荐。谢谢！

adum4165挂在HUB上行侧可以通信，挂在HUB下行侧无法通信，望不吝赐教，谢啦！ +1

图一图二大家谁能帮我看一下啊，谢啦！我画了2块电路板，在图二中，隔离器（ adum4165 ）在HUB的上游隔离PC，这种情况下，PC可以连接到HUB下游的USB接口摄像头，而在图一中，我把 adum4165 放在了HUB下游隔离后面的USB接口摄像头就连接不上了，另外一个没隔离的接口是可以连接上的，是adum4165不能放在HUB下游吗？

ADM2582 工作模式切换造成RX引脚数据干扰 0
Answered

问题现象：当串口波特率高于1.5Mbps时，串口会收到无效数据。当前问题定位：通过示波器可以发现，当DE引脚由高电平转为低电平时（收发器由发送模式转为接受模式），RX引脚上会出现一个低电平信号，MCU会误认为此信号时起始信号，导致串口触发接收中断。问题分析：低波特率时现象任然存在，只是当波特率高于1.5M时，MCU才会误判这个问题如何解决？原理图波形图：

MAX14949EWE+能否直接替代MAX14946EWE+ 0
Answered

我司做的板子上用到了MAX14946EWE+但最近不好买到，请问能直接用MAX14949EWE+来直接替代吗？我看手册功能封装都一样，隔离电压 MAX14949还要更好一些。

RS485 节点超出手册上限224个后，如何再进行扩展？ 0
Answered

如下图所示，系统整条RS485通路上计划挂载300个节点，配套的RS485收发器为LTC2862。但手册描述LTC2862最多支持224个节点。应该如何拓展到300个节点呢？请各位专家赐教，谢谢！

我在使用Max22216控制电磁阀时，VM为24V，电磁阀电阻为240欧，我使用CDR模式进行闭环控制，我设置DC_L2H为90mA，DC_H为60mA，最终电流稳定在60mA，但会产生一个故障告警HHF，调大L2H_TIME或者改大kp，仍然报这个错误，调小DC_L2H的值，问题依旧存在。
