TPS652170: Battery PMIC part selection for various power paths

SK
Intellectual 280 points
Part Number: TPS652170

Tool/software:

Hi TI partners,

Could anyone please suggest the battery powered PMIC for various power paths?

Below specification:

Vin: battery 18650 3.7~4.2V

The various power rails output:

Vout1: 3.3V/1A or above

Vout2: 5V/500mA or above

The rival chip is LTC3586 from LinearTech.

I found that the TSP652170, but it could not output 5V power from 3.7~4.2V input power.

Thanks so much.

SK.

    Hi SK, 

    We don't have many PMICs in our portfolio that integrate a 5V boost converter,

    I believe the 5V boost on the LP87702-Q1 can only support 2.8 -4 V input voltage. and has 2 additional bucks that can support the 3.3V rail. 

    It may also be worth asking the Battery Management Group if they have any device recommendations, since some of their products may have integrated boosts or power path,
    Like BQ25190. Please create a thread under a BQ part number to be directed to these device experts.

    Best Regards, 
    Sarah
