Part Number: BQ25910 Hi TI,
I am investigating the usage of BQ25910. I am curious about the control principles. Here are my two questions.
1. In the datasheet of BQ25910, it is stated that the device is operated for a fixed frequency. "The fixed…
Part Number: BQ25910 Hi Team,
Could you please confirm that what is the default value for the EN_CHG?
I observed that there is 0h for '3' on the headline, is it means that the default value for EN_CHG is disable? Thank you.
Sincerely
Fr…
Part Number: BQ25910 Hello , Ti experts:
I have question toward the caux of the bq25910, I know this cap need to be precharged to the 1/2 vin voltage but not detail, could you give me a brief block diagram to illustrate the this caux function in the…
Part Number: BQ25910 Hello charger team,
one question from guiding reference schematic of BQ25910, need to clarify the purpose of 'IND_SNS' pin.
I guess it would work for Vout sensing to adjust PWM switching. but in actual, this charger regulates…

Hi Michael,
In general, TI recommends 10uF capacitor by taking into consideration heavy DC de-rating, which will yield a final capacitance value around 2uF. Reducing the capacitance value will affect various aspects of the converter as you pointed out…
Part Number: BQ25910 Hi TI team,
In page 20 of BQ25910 datasheet, it says "The kelvin connections to the battery can be made via a 100-Ω resistor".
The 100Ω resistor is needed or not? Why?
Thanks!
