Tool/software:
Hello,
We use BQ25713 charger for 1S (4.2V) Battery and it charging via 5V/1A TYPE-C USB Adapter.
We've filled below successfully;
ChargeOption0() -> 0x020E
ChargeCurrent() -> 0x0580 (1408mA)
MaxChargeVoltage() -> 0x1068 (4200mV)
Measured;
CHRG_OK: 3V
Vin: 5V
VSYS: 4.2V
VBAT: 3.5V
REGN: 5.4V
ILIM_HIZ: 1.9V
ILIM_HIZ PIN -> 0x32[7]: 0 (Disabled)
I've applied 2.4.1 Charge Function from BQ25713EVM.
When I take measurements, charge voltage is ok but charge current is still zero.
I've noticed that mistakes;
We have pulled CELL_BATPRESZ to 3.3V instead of VDDA by mistake (I guess it is ok for 1S battery)
We used a 1nF capacitor instead of a 1-μF capacitor from VDDA to power ground
and I will be glad to know our other mistakes on schematic if there is.
Here schematic;
Kind Regards,
Volk
