BQ51021: WPC Receivers with I2C support - EVM availability

Part Number: BQ51021
Other Parts Discussed in Thread: BQ51222, , BQ51221

Tool/software:

I have 3 questions regarding your WPC receiver options with I2C:

1. It looks like there are 3 WPC receivers currently active that support I2C configuration: the BQ51021, BQ51221, and BQ51222.  Are EVMs available for any of them?  I can't find them through reputable distributors.

2. Are these parts still recommended for new designs?

3. Are the I2C register configurations non-volatile and persist over a power cycle?  (I think the answer is no, but wanted to confirm)

Thank you

    Sorry but EVM are not available for the units.

    They are still active. The BQ51021 is the only one I would recommend of the three.  BQ51221 / 222 are dual mode device with additional circuit which complicate operations.

    Sorry but no the register will reset with power cycle.
