【经验】如何解决SI32176-C版本SLIC芯片的设备无馈电现象?
笔者最近在调试SILICON LABS的单通道SLIC芯片SI32176时发现,在软件没有做任何改动的情况下,用SI32176-B版本的设备运行正常,但用SI32176-C版本芯片的设备都无馈电。为什么会有这样的现象产生呢?于是我们做了以下尝试:
第一步,从芯片的外观来看,两个版本的芯片的尺寸与封装完全一样,可以直接互换。因此将两个版本的芯片拆下来,并交换了位置,发现问题现象随着芯片走,由此判断外围电路都是正常的,问题与芯片本身有关。
第二步,通过与世强的FAE沟通问题现象,得知SI32176的两个版本外围DC-DC升压部分有区别。SI32176-C版本集成度更高,外围的DC-DC升压部分电路更简单。通过查看应用手册AN340,里面分别列出两个版本的Flyback DC-DC原理图。按C版本的DC-DC 原理图重新修改电路。
图1:SI32176-B 版本Flyback DC-DC 原理图
图2: SI32176-C 版本Flyback DC-DC 原理图
第三步,检查软件部分是否有差异。通过查看Silicon Labs提供的软件API包里面发现两个版本有不同的patch文件。通过选择Si3217x_patch_C_FB_2.14JUN18.c重新编译代码。如下图所示。
最后,将编译好的程序重新烧入到MCU中测试,测量Vbat电压有90V左右。DC-DC已正常。接入电话测试馈电正常。
以上是个人的一点调试心得,告诉大家免得大家在调试遇到同样的问题时走弯路。总得来讲Silicon Labs的SLIC芯片提供的API及说明文档非常详细,加上世强的技术支持移植过程非常快。SI32176芯片本身体积小,功耗低,不需要外加散热片,非常不错的一款芯片。
