Other Parts Discussed in Thread: CC1350
Hi experts,
I have designed my custom PCB using cc1350 LP reference and MSP430 using structure as below:
I use a power switch to turn on/off power for main power of CC1350 board. After i turn off the power, using multimeter to measure Vin of cc1350 i got voltage is immediately down from 3.3V to 2.2V and then take along time to down to 0V. i disconnect TX line of MSP430 and do the same thing as above, but i got the voltage is suddenly down to 0.6V and then slowly down to 0V. Could you tell me what is my problems and what do i have to do to fix it?
Thank you very much!
