Part Number: BQ25730 Other Parts Discussed in Thread: BQ25713B , BQ25713 a new project needs to switch from BQ25713B to BQ25730. Currently, the charging and voltage are normal, but the test found that the PTM function of the two chips is not compatible…
Part Number: BQ25730 Tool/software: Hello.
We are developing a charger based on the BQ25730 but we are wondering if it would be possible to use a digipot to control the reference voltage of VDDA for CELL_BATPREST and in this way select the number of…
Part Number: BQ25730 Tool/software: I am creating a circuit that includes the BQ25730 to charge a single high capacity LiPo cell. I have three questions that I had trouble getting from the datasheet: 1. Can I omit the USB OTG functionality completely…
Part Number: BQ25730 Tool/software: When I plug my 5S battery into the PCBA, a large voltage spike is generated that damages components. Can any BQ25730 settings be changed to help with the spike?
Part Number: BQ25730 Tool/software: Hello Team,
Could you please clarify how the BQ25730 charger IC is powered in battery-only condition? The datasheet mentions that the IC is powered from VBAT in such cases, but there is no explicit VBAT pin on the…
Part Number: BQ25730 Hello Sir:
Please refer our questions as below.
1. If adapter source is 9V/6A for VIN, our battery is 2s, which charge voltage is 8.4V, can we config min VSYS to 9V?
2. does bq25730 support temperature protection on battery…
Part Number: BQ25730 Tool/software: Hello, testing a custom design using BQ25730. Test is focused on utilizing OTG to use battery source to drive load on VBUS.
With the default 5V OTG voltage and 6000 mA OTG current limit I am unable to pull more than…
Part Number: BQ25730 Tool/software: Hi team：
Directly disconnecting the AC power supply causes the PSU to have no input. Due to the PSU, the voltage at the VBUS terminal slowly drops. When the voltage at the VBUS terminal drops to 3V, the VBUS terminal…
Part Number: BQ25730
Tool/software:
Dear Sirs and Madams,
We are verifying the power consumption and temperature rise of the BQ25730.
We measured the package surface temperature of the BQ25730 during charging and found it to be 75°C.
I would…
Part Number: BQ25730 Hi
The customer test with BQ25730. Get the voltages of VSYS and VBAT through the 0x2D2C register. The original 16bit value obtained is: 9E9Ch.
According to the parameters in the specification, LSB: 0.064V, then VSYS and VBAT are…
