Other Parts Discussed in Thread: UCC28600 , BQ24600 I AM USING IC UCC28600 FOR 65W SUPPLY AT 18V@3.6A .....BUT WHILE LOAD CONDITION IC IS NOT GETTING SOFT STARTED.
MEANS IC IS NOT SOFT STARTED IN LOAD CONDITION.PLEASE CLARIFY THE SAME
Check out the bq24600 multi chemistry charger supporting 1 to 6 cells. The input over voltage protection, input under voltage lock out and the battery over voltage protection features should serve your needs.
I need more information and maybe some waveforms of each pin of the IC.
Is the input voltage at least 18VDC?
Is the battery at least 12.4V? If below ~12V the charger will be in precharge and one gets 1/10 the current.
I would suggest using…
bqstroller calculation tools_V1.5.xls Hi,
I have used a excel sheet "bqstroller calculatin tools_V1.5" shared by TI.
same values I have used which is suggested by that calculator.
I have also attached the excel sheet for your reference

The PTN78020 current limiing cannot be controlled. It reacts to a loading up to 6 Amps. I suggest a ion battery contol solution such as http://focus.ti.com/lit/ds/symlink/bq24600.pdf for best results .
The BTST goes only to 5V even the battery is attached. I also got this problem, but i use the bq24600.
In this status, i found the high side MOSFET driver is always turn off. The Voltage of REGN Pin is 6V,if you don't use the schottky diode, use the…
Q1 is for a reverse blocking circuit. It blocks the reverse current from battery to input source.
Q2 is for an inrush current control circuit. The battery is not connectted to the system directly. The inrush current is decide by the Q2 turn-on speed…
Part Number: TIDA-00982 Hi, we are trying to build a 2S battery charger for a nano non-military drone. Taking the TIDA-00982 as a reference.
For adapting to our requirements:
1. We would want to eliminate the use of Pack Out connector since the BMS…

Hi TI Experts,
I am posting this because I need help on a system, I am designing a power unit using Li-Ion batteries, this will be a supply for other products,
I saw on…
Other Parts Discussed in Thread: BQ2954 , BQ2054 , BQ24600 Hello,
i am currently working at designing a battery charger for charging a 6-Cell LiIon Battery pack (with built-in protection/balancing).
Target charge current is 5A, charge voltage 4…
