Part Number: BQ25306 Hi I am designing a portable battery powered device using 2S 18650 batteries and have chosen the BQ25306 as the charger. I have looked through the forum and read a few interesting problems of which I have included in my design but…
Part Number: BQ25306 Hi Team, Can you suggest a power MOSFET to be paired with BQ25306 for the customer requirement below: In the customer's application, Device is powered with Li-ion battery. Using BQ25306 for the charging the battery. They like to use…
Part Number: BQ25306 Hi
There are then evaluated using the client BQ25306, input 12V, 1.5A for setting 2cell lithium battery. According to the specification, the charging current will stop if the charging current is lower than 0.15A. Customers are worried…
Part Number: BQ25302 Other Parts Discussed in Thread: BQ25303J , , BQ25306 , BQ25300 When battery is shorted, if the high-side FET (HSFET) of the charger turns on then there will be a direct low impedance path to GND resulting in high current through the…
Part Number: BQ25306 Hi,
There is audible noise in BQ25306 when current is 1A~3A.
It's disappeared when charging current is under 1A at CV mode after CC mode.
Due to small application, it's difficult to provide waveform.
When C40 FF capacitor…
Part Number: BQ25302 Other Parts Discussed in Thread: BQ25303J , , BQ25306 , BQ25300 The battery chargers BQ25300, BQ25302, BQ25306, BQ25303J control the charging enable and disable by the /EN and POL pins.
To enable charging, /EN and POL need to have opposite…
Part Number: BQ25306 Hi
The customer design the schematic to charge 2 series battery, charging voltage 8.4V/0.5A
Attached the schematic and inductance information.
Power-on test, when the battery is not inserted, the charger output is about 3.4V, SW…
Part Number: BQ25306 Hello,
The context:
I'm working on a project that needs to include a charger for two LiFePo4 battery cells in series. I'm planning to use BQ25306 for this purpose. The device will use two Cylindrical standard size (18650 or above…
