BQ51050B: Design Help

Part Number: BQ51050B

Hello all,

A student ask,

" I am developing a device, which comprises a BQ51050B. I am having some problem in the design using the DSBGA package. In particular I would ask if the pins with the same name must be connected together or not, if they are connected together inside the device. Moreover I would know how the pins, corresponding to RECT, CLAMP1, CLAMP2, FOD, could be routed to the external part of the device, as the pins are very small and they are surrounded by other pins.
Also, could you provide example design which uses this component with DSBGA package. "

Could anyone help me with this please?

Thank you in advance.

  • Hello
    Thanks for posting to the Wireless Power Forum.
    I highly recommend connecting all the pins for the DSBGA package. A layout example can be found in the data sheet, figure 38.
    Also this device is available in a QFN package that is larger but easier to layout and manufacture.
