Part Number: BQ24125 Other Parts Discussed in Thread: BQ24171 , BQ24133 Hi,
I implemented in my board the power-path selection circuit from the document SLUA376 topology 3. For Q1, Q2 and Q3 I have selected DMP3037LSS-13 and for the third transistor, 2N7002ET1G…
Part Number: BQ24125 Hello everyone,
I have a question regarding my design which uses the BQ24125 Standalone 1-3 cell 2A synchronous Buck battery charger with enhanced EMI performance to charge an 11.1V 5.2Ah Li-ion battery. Currently, I am using a 15V…
HI Jeff, Thanks for the support. This is just the simplified our circuit around BQ24125 . You can see that the Rsns is before the top of FB register. I’d appreciate it if you could check our circuit. If you need the waveform to check, please let…
Hi Jeff.
I bought two EVAL boards and they charge my batteries correctly, as expected. I will start checking why in my board is not working the same way.
I based my design in a datasheet example (figure 24) that shows a circuit that does not need a power…
Part Number: BQ24125 Hello team,
I received a question from the customer.
The datasheet shows MMBZ18VALT1 for MOSFET protection as an option, are there any points to be considered when selecting a TVS Zener diode? For example, breakdown voltage, etc. …
Part Number: BQ24125 3S (12.6V) Li ion battery charger design with following specs and Component values
Vin =16V
RSNS=0.1R
R(ISET1)=9K75
R(ISET2)=20K
I am not using NTC so the TS PIN voltage divider resistors are 10K,10K Respectively
PG LED =ON(GLOWING…
Part Number: BQ24125 Other Parts Discussed in Thread: BQ24123 , BQ25125 Hi Team, Our customer has a question about the feedback resistors on BQ24125.The resistor network connected between the battery and FB pin determines the the charger output voltage.
…
Part Number: BQ24125 Hi Team,
I want to use the BQ24125 to charge a 3S Lithium Ion battery pack. The datasheet doesn't really talk about charging with a 3S pack in detail, but it does talk a little bit about the Feedback pin. Do I just need to set the…
Part Number: BQ24125 Hello,
I have created a charger circuit For 3Cell Li ion Battery BUT After reaching the Battery Voltage 12.22V the battery is not charging but the STAT1 and STAT2 LED'S status are as below
Vin =16V
At Output Pin with Load(Battery…
