Part Number: BQ24075
Our issue:
1. charger connected to USB power source
2. battery disconnected
3. across the battery terminals (BATTERY_IN to GND) we read a fluctuating voltage anywhere from 0 - 5 V...
4. when we plug the battery in the voltage across the terminal is the battery voltage (about 4.2V) and there are no issues
5. We are assuming this is because CE is pulled low so charging is enabled even though batter not in, is there any way around this?
