Part Number: BQ27520EVM Hi team,
The phenomenon:
1. The device cannot turn on and the battery is fully charged in a low temperature (10°C) environment.
2. The charge through the bq27520 is 0 and the temperature is 3 degrees.
3. Scope: Jiangxi province…
Your Ra Base value is extremely high. 307 equals 307*4 = 1228mOhm. With a load of 1494mA (avg I last run) and a full charge OCV of 4200mV, this would cause an immediate voltage drop to 4200mV - 1835mV = 2365mV, which is below Terminate Voltage + Delta…
