Part Number: BQ51050B
Other Parts Discussed in Thread: BQ500212AEVM-550,

Hi,

I am planning to use bq51050B to charge the Li Poly battery. So, which is the transmitter part suitable for this receiver. Does EVM is available for receiver and transmitter for evaluation.

My charge current requirement is below 400 mA and charge voltage is 4.2V

bq500212AEVM-550 PWR550 is suggested in TIDA-00329 test report. But, in digikey bq500212AEVM-550 PWR550 is displayed as obsolete. Could you please confirm whether this part is obsolete or not

Regards,

Sanjay

    Hi Sanjay,

    Since the BQ51050B is Qi compliant, you could begin evaluation with an off the shelf transmitter that is Qi Compliant. Since the charge current is below 400mA, I would imagine you would want to terminate at 80mA or lower. What is your battery capacity?

    You could take a look at some of the other receivers with a discrete charger which will give you greater flexibility. Yes the transmitters are in limited support for existing customers so they are not recommended for newer designs. 

    Let us know if you have any questions.

    Regards,

    Hi Gautham,

    Thanks for the reply.

    Could you please recommend any part number for off the shelf transmitter that is Qi Compliant and the battery capacity would be 800mAh to 1Ah.

    As you suggested, Could you please name some receivers with a discrete charger, so that I can check for the feasibility

    Thanks & Regards

    Sanjay

    Hell Sanjay

    I can assist with this question.

    A good off the shelf wireless charger to test with is the TYLT VU or TYLT VU SOLO, both are available from Amazon.  This is a Qi certified wireless power transmitter rated up to 5W output power.

    The BQ51050BEVM-764 (BQ51050B EVM), is available from Digi-Key.
