Other Parts Discussed in Thread: MSP430F5529, MSP-EXP430F5529LP, LMP90100,
I got a new BOOSTXL-BAKPAKMKII and was using it to power up my MSP430F5529. The system was working well and at some point it stopped. First, I thought that the battery was discharged completely. So, I plugged the fuel tank to desktop computer via USB cable in order to charge it. The "charge active" LED was on when I first plugged it. I left it for almost 48 hours, not on purpose. However, when I came back the LED was off. I tried it but the output is approx. 2 Volts. I plugged it again but this time the LED stayed OFF. I checked the connection and then I plugged it carefully and I saw that the LED is blinks for like tenth of a second and then goes OFF. I left it in charge for a while.
Then I used a multimeter to measure the output voltages from both 3.3V and 5V pins. They both show around 1.5Volts. Interestingly both output decreases in a stable manner as they were discharging over a capacitor. More surprisingly even though I changed the switch from "Connect" to "Disconnect", I was be able to see the same output values around 1 Volt and the discharging patter. Now both output show 0 Volts, as they were discharged.
Could you please help me about this problem?
