BQ32000: need cap for crystal?

Part Number: BQ32000

does the bq32000 need a cap at the OSCI/OSCO pins parallel to the crystal? Is CL of 12pF inside the bq32000?

What other external components are needed? The schematic in chapter 8.2 Typical Application shows cap for VCC and Vback.

Regards, Holger

  • Hi Holger,

    No additional external load capacitance is needed if the selected crystal has load capacitance of 12pF. I expect internal capacitance inside BQ32000 would be about 24pF on XIN and XOUT. 

    In addition to the decoupling caps, make sure to place the I2C pullup resistors.

    Kind regards,
