Part Number: BQ27532-G1 Other Parts Discussed in Thread: BQ25600 , BQ24251 Hi everybody,
the datasheet of BQ27532-G1 recommends a charger of the BQ2425x series, which is not recommended for new designs. The product page of BQ24251 names BQ25600 and…
Irene,
1. If the charger completely shuts down without VBUS and VBAT, all the register settings will not be saved. When VBUS rises above VVBUS_UVLOZ or BAT rises above VBAT_UVLOZ , I2C interface is ready for communication and all the registers are reset…
Hi Madhu,
Regarding 1, no. The external PFET is optional to provide a lower resistance path in parallel with the BATFET when the charger is in HiZ mode.
Regarding 2, if D+ and D- are unconnected the input current limit auto sets to 100mA. I suggested…
Hi,
The available sample code is available at the link below. The customer may follow the same principle and convert the code to other platform as needed.

The is no PMU or PMIC which can charge a battery up to 2A current.
The TPS65217 is the latest PMIC we released with a battery charger, but the default current is 500mA (max 700mA).
The TPS65218D0 is the next generation PMIC, which removes the integrated…
Hi Gil,
Most likely the solar panel voltage is hovering above the sleep comparator threshold.
I don't recommend running the solar panel in an open loop, it is better if the device has an input voltage regulation loop (in the chargers we call it…
Hi Jeong,
On the BQ25601 charge is enabled by default. The IC does not detect battery connection, it will always attempts to charge. When no battery is connected IC will regulate the voltage of the BAT pin capacitor as if it is a small battery. Then…
Chandan,
1. Please follow the d/s. The acceptable range for charge current is 300 mA to 3000 mA
2. For RICHG = 1100 Ω, VBAT = 3.1V or 3.8V, TJ = –40°C - 85°C, Fast charge current accuracy is between 0.516A and .715A.

Okay perfect. I'm glad you found a solution.
Can the MCU also communicate with the charger? I only say that because you can use it to make programming the charger easier by using something like bq25601 or the bq25600 through I2C.
Regards,
