TPS65217: PMIC for BeagleBone Black

Part Number: TPS65217
Other Parts Discussed in Thread: , BQ24259, TPS65218D0, TPS650250

Hi Team,

A customer is working on a design based on BeagleBone Black module that uses the TPS65217 as the power management IC for an AM3358BZCZ100 processor. However, the TPS65217 doesn't support enough charging current as recommended for his 1800mAH battery (900mAH charge rate is desired).

Additionally, he needs to provide 5V power for a USB port while operating off the battery which will require additional converter since 5V is not available from TPS65217 when operating off battery.

He would like to ask for alternative components to use in this application. I have checked our product lines but a similar device, TPS652170, can't meet the requirements. Can you please suggest an alternative solution.

Regards,

Danilo

    For a battery charger with higher charging current, you will need to look at bq battery charger products (like the BQ24259 that has integrated USB OTG to generate 5V output from the battery).

    If you will not use the battery charger in the TPS65217 PMIC, then you can consider using TPS65218D0 or TPS650250 as the PMIC for the processor to reduce overall BOM cost.
