Other Parts Discussed in Thread: CC2640
Tool/software: Code Composer Studio
Hi,
I made a PCB with CC2640R2F, one battery and other electrical components.
Tha battery doesn't supply the CC2640 but the other part. I connect the battery at one ADC input of CC2640 to monitor his state, but when I power off the circuit and the CC2640 is down, I find on the power supply line of CC2640 2.6 V, and the battery current is very large, as if it supply CC2640 also.
If I disconnect the battery of ADC input the voltage it's 0.3 V on the supply line of CC2640 and the current of battery is ok.
Why is it appened? How can I avoid it?
Thanks.
Best regards.
Giuseppe
