BQ25622: Pre-charge current and termination current settings

Tiger Yeh

Part Number: BQ25622

Hi,

We found that the pre-charge current(REG0x10) and termination charge current(REG0x12) are always with the default value(POR), no matter how we modify them.

But other settings like charge current(REG0x02) is fine.

Is there any conditions we missed?

Thanks and Best regards,

Tiger

Hi Tiger,

When the pre-charge current(REG0x10) and termination charge current(REG0x12) settings do not change,

1. What are the charger operating conditions such as VBUS (voltage at VBUS pin), IVBUS, VBAT (voltage at BAT pin), IBAT, VSYS, ISYS?

2. Could you please provide all register readings of the charger?

Thanks a lot,

Ning.
