Other Parts Discussed in Thread: BQ25150,
Hi
I have a question about register settings for BQ25150.
I use the BQ25150EVM to power devices that consume about 50mA of current.
I set a charging current of 70mA to the register, but the charging current supplies 11mA to the device and does not rise to the register setting value.
Moreover, even if the power supply to the device is stopped, the charging current is 30mA and does not rise to the register set value.
The maximum charging current 70mA (register: 0x13 ICHG_CTRL, data: 0x38) and the maximum feeding current 200mA (register: 0x19 ILIMCTRL, data: 0x03) are written as the setting values for the register.
Is there anything I should be aware of other than the above register settings?
The circuit supplies power as follows.
・ Powering 4V lithium-ion battery to VBAT
・ Power supply from VLDO to device 1.8VI2C sensor
・ Power to the device from 3p3V of TPS78233DDCT on BQ25150
・ 5V charging from regulated power supply to VIN
I can explain in more detail by email.
