BQ25616: Schematic Review Request for BQ25616 and TLV61070

Part Number: BQ25616

Tool/software:

Dear TI Support Team,

I am designing a system that uses the BQ25616 as the charging IC and the TLV61070 as the LED driver.

  • KV_VCC is 3.3V.
  • LED_5V requires a supply of 550mA.
  • Components within the black box are connected to the MCU.

Could you please review my schematic and component values to ensure they are correct? I have attached the schematic for your reference. Let me know if additional details are needed.

Thank you for your assistance!

    Hello,

    My schematic review is as follows:

    1. Please put the BAT capacitor close to BAT pin.

    2. The charge regulation voltage is 4.208 V.

    3. The pullup for the logic lines is 100kOhm, we recommend a 10kOhm for a slightly stronger pullup. Please test according to your application.

    Please post another thread for the TLV61070 as the main IC so the appropriate team can review the schematic for that device.

    Regards,

    Mike Emanuel
