Hello, we are using the BQ25303J in conjunction with an STC3100 fuel gauge in a client application. The issue is the fuel gauge is always saturated when a USB plug is connected to the device reporting always 100%.
since the SW node…
Hello,
A 1% resistor is being used for Richg and for the min and max values in the specification the BQ25303J device is tested from -40 °C to 125°C.
Best Regards,
