摘要
为了解决加电控制模块70℃高温下异常复位,导致系统中其他设备无法正常工作的问题,针对模块断电检测元的电路做了详细的分析,提出二极管在70℃高温下性能下降是影响复位异常的关键因素。首先选择合适型号的二极管,其次随机选择3件待调加电控制模块进行试验并采集关键点位在常温和70℃高温下的试验数据,最后更换性能更好的二极管进行同样的试验并记录对应数据进行对比分析。试验结果表明,模块装配性能更好的二极管成功解决了加电控制模块高温下异常复位的问题。
In order to solve the problem that other equipment in the system cannot work normally due to abnormal reset of the power on control module at high temperature of 70℃,the circuit of the module power off detector is analyzed in detail.It is pointed out that the degradation of diode performance at 70℃ is the key factor affecting reset abnormality.First select the appropriate type of diode,then randomly select three control modules to be adjusted for power on for test and collect the test data at the key points at room temperature and 70℃,finally replace the diode with better performance for the same test and record the corresponding data for comparative analysis.The test results show that the diode with better assembly performance of the module successfully solves the problem of abnormal reset of the power on control module at high temperature.
