TIDA-00120: 30A charging current needed

Hi,

Please see the description:

Hi,

Thanks for your reply. The actual part number related we are using is BQ24650. And I heard that the maximum charging current of it is 10A. Is it correct, then, can it also be used for charging current up to 30A? 

I think this problem mostly lies on the charger not MSP430. I will change your thread to another topic.

What do you mean by 'Charger'? Can you also answer to my questions below?

1. TIDA-00120 software should be transferred to MSP430F5132 by user? If so, how can we do it?

2. You wrote above that we should change the FET to TO-220 package to increase the charging current upto 40A. I found that below two items are two FET used in TIDA-00120. 

CSD18502Q5B

CSD18532Q5B

Are above two all the FET that should be changed to TO-220 package? Then, can you let me know the exact part numbers of TO-220 package for above FET?

Hello,

Can you give me your answer to my message above? Please understand that it's very urgent for us and we don't have much time.

It seems no one help you. OK, I will try to answer your question. I must say I know nothing about charger and this design.

1. TIDA-00120 software should be transferred to MSP430F5132 by user? If so, how can we do it?

The software source code is here if you install the GUI:

2. Are above two all the FET that should be changed to TO-220 package? Then, can you let me know the exact part numbers of TO-220 package for above FET?

I can't find the T0-220 package in the datasheet. Use CSD18502Q5B as an example. The reason why you can't use it is the temperature will be over spec. My advice is:

a. Add a passive radiator to these two MOSFETs. You can calculate according to the parameters in datasheet to make sure the temperature will not over spec. 

b. Find change another N-MOSFET or P-MOSFET to meet your requirement. For this part I have no experience.

Hello, 

Thanks for your answer.

MSP430F5132 already includes the software for TIDA-00120? 

Hello,

I mean if we buy MSP430F5132 from TI, does it already include the software for TIDA-00120? In this case, we don't need to upload the software  to this MSP430F5132?

This question might should awkward to you. But, please understand that we need your help here and hope you can give me your answer as soon as possible.
