Part Number:MSP430F5659
Hello MSP430 community,
I'm facing an issue related to the power supply:
My Setup:I designed a board in which my MSP430F5659 is interfaced with an external host through USB.
The issue: with MSP430 connected to host through USB, when I power off my board, the 3V3 level decreases to around 1V8 and not 0V (and still at 1V8 even after hours). which causes an issue during the next startup: The MSP430 does not startup well.
I have reviewed my USB design following this guide, and don't see the issue ?
Regards,
