我有一个DA14580通过SPI与MCU对话。当DA进入扩展睡眠时,它会关闭SPI(在arch_turn_peripherals_off()中)。然而,由于各种原因,单片机必须保持MOSI和SCK线在休眠期间拉高。不幸的是,这似乎导致大量泄漏电流流入DA引脚,大约140 uA I测量。它应该很容易验证。

这个泄漏电流对我们的应用程序来说太大了(我们需要整个系统在睡眠期间低于20 uA)。有什么办法可以预防吗?

谢谢,
保罗。< / p > < / div > < / div > < / div > < div class =”字段field-name-field-forum-keywords field-type-taxonomy-term-reference field-label-above”> < div class = "字段标签" >关键词:,< / div > < div class = "字段条目" > < div class =”field-item甚至“> < a href = " / resource-keywords / gpio-leakage-current”“=“skos:概念”属性=“rdfs: label skos: prefLabel” datatype="">GPIO leakage current
