Hello,
We are working on BQ25713 to charge 1S battery(18650 2800mAh Li-on 8C). We've filled registers below;
1) BQ25713_REG_CHARGE_CURRENT - Value: 0x0580 (1408mA)
2) BQ25713_REG_MAX_CHARGE_VOLTAGE Value: 0x1068 (4200mV)
3) BQ25713_REG_INPUT_VOLTAGE Value: 0x0680 (5056mV)
4) BQ25713_REG_MIN_SYSTEM_VOLTAGE Value: 0x0D00 (3328mV)
5) BQ25713_REG_IIN_HOST Value: 0x0C80 (3200mA)
6) BQ25713_REG_IIN_DPM Value: 0x09C4 (2500mA)
7) BQ25713_REG_CHARGE_OPTION_0_EN_LWPWR // Disable
8) BQ25713_REG_CHARGE_OPTION_2_EN_EXTILIM // Disable
9) BQ25713_REG_CHARGE_OPTION_0_CHRG_INHIBIT // Disable
10) BQ25713_REG_PROCHOT_OPTION_1 Value: 0x00FF (255)
We were unable to successfully charge the battery. Is there a missing register that needs to be filled in or wrong filled register?
CHARGE_OK is HIGH

Hi,
Thank you for quick reply.
I've checked BQ25713EVM user guide and applied "2.4.1 Charge Function" but it doesn't change.
Is there anyting advice about that?
King Regards,
Volk
3) BQ25713_REG_INPUT_VOLTAGE Value: 0x0680 (5056mV)
This is not needed. Set to zero.
