TIDA-00883: question about TIDA-00883

Part Number: TIDA-00883

Tool/software:

Hi teams,

Here is MM FAE Chris, i am promoting TIDA-00883 in my customer Lango. and the customer have the follow questions:

1: Single cell: 3.2V 102AH, 3.2V 180AH, 3.2V 314AH. These three cells are the cells that customers are about to use. They have large capacity. Can 40Z50 be adapted? I have read the application document that it can be achieved by scaling parameters. I want to know more implementation details;
2: The charging and discharging currents are relatively large. The charging current of a single cell and two cells in series is close to 100A, and the charging current of three cells in series reaches about 70A; the discharge is generally 0.5P discharge, and the current is also about 50-100A; can we meet such requirements?

I hope you can help me solve customer problems and win the case together.

Best Regards

Chris

    Hi Chris,

    Yes, I believe this can be achieved by scaling the parameters, however in this case, the sense resistor will also need to be scaled to a value to keep the voltage difference between the SRN/SRP pins to +/- 100mV. Scaling the sense resistor up in this case could also lead to a lose in resolution of the current reading. 

    I believe the FETs will also have to be chosen carefully, or have a parallel FET system, to accommodate for the high currents.

    Regards,
