Request for PMIC Recommendation with Specific Features

Dear Texas Instruments Support Team,

We are looking for a power management IC (PMIC) that meets the following specifications for our application:

  • Battery Input: 3.7V to 4.2V (Li-ion/Li-poly)

  • Battery Charging Current: 750mA to 800mA

  • Buck Regulators: At least two buck converters with an output current of 250mA to 300mA each

  • Load Switch: Integrated load switch with an enable pin

  • Fuel Gauge: Integrated battery fuel gauge for accurate battery state monitoring

  • Additional Requirements:

    • Compact package suitable for space-constrained designs

    • Latest recommended solution with efficient power management

Could you please suggest the latest compact PMIC from TI that meets these requirements?

Looking forward to your recommendations.

    Hi Parth, 

    We have limited PMIC products that include Li+ charger/battery support, so we may not have a PMIC that exactly matches these specifications.

    The best recommendation would be TPS65217 / TPS652170 (user-programmable version)

    • Li-ion / Li-polymer Battery Charger
    • Max 700 mA charge current, 
    • 3 Buck Converters, up to 1.2 A
    • (2 LDOs, up to 100 mA)
    • 2 Load switches, can be programmed to a sequence, or enabled with register bit via I2C
    • MUX_OUT pin can be used to approximate battery level
    • Undervoltage Lockout and Battery Fault Comparator
    • I2C Interface
    • VQFN package (6 mm x 6mm)

    The next closest alternative would be TPS65070x:

    • Li-ion / Li-polymer Battery Charger 
    • Max 1.5 A charge current
    • 3 Buck Converters, up to 1.5 A
    • 2 LDOs, up to 200 mA
    • Undervoltage Lockout and Battery Fault Comparator
    • I2C Interface
    • VQFN package (6 mm x 6 mm)

     Let me know if you have any further questions. 

    Best Regards, 
    Sarah
