TPS65000: Searching Highly Integrated PMIC Solutions.

Part Number: TPS65000
Other Parts Discussed in Thread: BQ24075, TPS563252, TPS65217

Tool/software:

Hello, E2E Community.

I'm looking for the new Integrated PMIC to change project design.
The previous design used a BQ24075 battery charger, a TPS563252 buck converter, and two other LDOs, and I want to integrate this power supply part.
My project is a portable device containing lithium polymer battery, and the requirement Features are as follows.

- Linear Battery Chargeing
　- 5V DC Adapter input
　- Single-Cell Li-Po Battery Charging / 4.2V, 650mA charge current
　- OVP and Battery Protection
　- PowerPath
　- Ship mode or Chip enable/disable (Device On/off by button press)

- Regulators
　- At least 2 adjustable LDOs and Buck-converter each
　- 1.8V ~ 3.3V voltage range select
　- 100mA or more current output

- I2C for control and monitoring
- QFN type IC package (BGA type are not acceptable due to PCB cost)

I would like to ask you to recommend a PMIC that meets these requirements.

Best regards,
Kim

    Hi Kim, 

    Thank you for your continued interest in using TI products in your design.

    I would recommend looking at the TPS65217:

    • Adjustable LDOs and Bucks
    • Linear Battery Charger with Power Path
    • Max 700 mA charge current, 
    • Supports 5V AC Adapter input
    • Undervoltage Lockout and Battery Fault Comparator
    • I2C Interface
    • VQFN package

    It may also be worth looking at the TPS65070x:

    • Fixed LDOs , but adjustable Bucks
    • Linear Battery Charger with Power Path
    • Max 1.5 A charge current
    • Supports 5V AC Adapter input
    • Undervoltage Lockout and Battery Fault Comparator
    • I2C Interface
    • VQFN package

    Best Regards,

    Hi, Sarah.

    Thank you for answering my recommendation request.

    The recommended part TPS65217 will be considered as candidates for use in the project.

    As an additional question, in the Datasheet, the TPS65217 is specialized in supplying power to AM335x processors and has a different part number depending on the default Power-Up sequence setting,

    If I use an other AP(e.g. nordic nRF5x series), does it not matter which part number I use?

    If it doesn't matter, do I just need to change the register map setting?

    Best Regards,

    Kim

    Hi Kim, 

    Yes this is correct, if you are using TPS65217 for a different processor, 
    you can adjust the power-up sequence setting with the SEQUENCE registers, and it would not matter which part number you use. 

    Best Regards, 
    Sarah
