BQ24170 EVM

hi

at the EVM bill of materials there are 2 columns 001 and 002.

what is each one referring to?

regarding pin 19 BATDRV - when using a 5V supply, and one battery cell of about 10A, do i need to pull down or up this pin, or connect only with serious resistor to the FET gate?

thanks,

Golan

    Hi Golan,

    The EVM bill of materials columns you are asking about are for the two different versions of the EVM we offer. EVM version -001 is for 5V input and 1-cell and the version -002 is optimized for 12 or 15V input and 1-3 cell charging.

    Please do not pull up or pull down the BATDRV pin.  I don't know what configuration you are using in your system. Please review the datasheet for several configuration examples (page 4- 7).

    If you are using the application schematic from Figure 1 of the datasheet with the appropriate changes for a 1 cell battery you will just need to have a serial resistor from BATDRV pin to the Q3 FET.  

    Best Regards,

    Rachel
