Hi team,
BQ26100 is used in SDZ power mode, as figure below shows. When use DSO to measure SDZ waveform, customer found the logic high voltage lower than 3.3 V and low logic voltage higher than zero. My question is:
1. Why the high level will be lower than 3.3V? Is there a diode in the SDZ pin and extra current flow into the SDZ pin, which result in voltage drop?
2. Why the o logic voltage level higher than 0V, is there any risk of mis-detect?
