Part Number: BQ24617 Other Parts Discussed in Thread: BQ24650 , BQ24630 , BQ24640 , BQ24610 , BQ24620 , BQ24616 , Do those TI's battery charger ICs ( bq24610, bq24616,bq24617, bq24620,bq24630, bq24640,bq24650) can reach 20A charging current? If no, which…
The datasheet attached does not include the charge profile. Do you have the information on the charge profile?
We do not have a charger today specifically made for SCiB.
The bq24620 is a charger for LiFePO4 with CC/CV charge profile and have a precharge…
Other Parts Discussed in Thread: BQ24640 , LM5122 One of our customer want us to suggest a device and solution that can charge a Super cap 12000F (2no’s in Parallel).
The input is 12V and they want charging voltage of 5.4V.
Battery team suggested…
Hello Danilo,
Input Case:
-Using 24 volts will work fine with the BQ24640 but you will need a a intermediate rail if 30 volt input is used.
-The charge current of 10A should be acheivable if the the right FETs and power components are selected…
John,
I would recommend the bq24640 if you plan on charging a super capacitor. The bq24640 allows charging from 0V whereas the bq24630 does not (no way to change this in the bq24630).
I will get back to you about the precharge timer being disabled…
Generally speaking, you can probably charge a super cap with TPS54821. You will almost certainly be charging the cap during SS time at the current limit, around 14.5 A. Your LC corner frequency will be quite low as well. It may limit the available BW…
hi Sonoki-san,
bq24640 doesn't have the pin for control the balance terminal. However, the bq24640 Vout can be set to 5V. If adding an external voltage divider using two matching resistor and connect the center tap to the balance terminal, it can be…
