Part Number: BQ24640 Tool/software: Hello TI Support team,
We are currently developing a system that is limited to ~82W Power Supply. It is required to boost Power Supply 1 (12.3VDC 6.7A: This is the max available we have to design around) to 19VDC to…
Part Number: BQ24640 Tool/software: Hi team,
1. May I know how we calculated the value of Cff on the datasheet's typical application circuit? 22pF is required? Are there any other acceptable capacitance?
2. On the EVM schematic, C25 is mounted but…
Part Number: BQ24640 Tool/software: My customer needs an indication for CC-Mode to know that the supercap final voltage is not yet met.
The Block-Diagram shows this current sink on page 11, and the customer wants to know if this pin always draws this…
Part Number: BQ24640 Hello, My customer has some questions as follows. Q1: 7.3.2 Output Current Regulation Regarding the output current regulation, which is the set maximum charging current, peak current, valley current, or average current? Q2: Charge…
Thanks Garrett! I had already seen the application note you provided, it has a lot of very useful information, but it still has some limitation regarding the application I'm working on: - Linear charger BQ25173 seems great on a lot of points (including…
Part Number: BQ24640 Hello,
We are using the super capacitor charging IC BQ24640RVAR to provide the power back up of our system when power off and for that we are using IC Part#BQ24640RVAR to charge the super capacitor - 4 in series with 100F/2.7V each…
Part Number: BQ24640EVM Other Parts Discussed in Thread: BQ24640 , Hi, a design of the BQ24640 has been made to charge 8 supercapacitors of 70F to 22.6V, and then has been implemented on the BQ24640EVM evaluation board.
The design has been tested and indeed…
