问题描述
<Jetson_Thor_Series_Modules_DesignGuide_DG12084001_v1.2> 中的5.3.2.3章节中的PWR_GOOD信号是指Thor模组中的MODULE_POWER_GOOD 管脚信号吗?以下是原文:
When the user connects the main power source, the Button MCU sends the power
enable signals to the module (VIN_PWR_ON) and enables MODULE_POWER_ON. This is
accomplished by having the ACOK signal driven high instead of pulled to GND.
The signal representing the power button to the Jetson Thor (POWER_BTN_N) will
continue following the power button (BUTTON_POWER_ON*) behavior. However, once the
power-ON sequence is initiated by the connection of the main power source, and ACOK
is driven high (by push-pull driver powered from 3V3_AO), the power button signals will
not affect the Button MCU behavior until the PWR_GOOD signal verification is complete.
