Does TI offer some PMIC with the following requirements?

Hi TI PMIC team,

We have some (very) special requirements for a PMIC. I was wondering if you guys could suggest something.

1) Solar Panel input: 18V, 1.5A, with MPPT or MPPC

2) Single Cell or Multi Cell Lithium Ion battery management:

     - Charging (CC - CV, etc)

     - Battery Gauging  

     - Battery Protection (Undervoltage, Overvoltage, overcurrent, temperature, etc)

     - Battery Balancing (if multicell device)

3) DC-DC Outputs:  

      -  5V, 3A

      - 12V, 4A or 5A

4) Host communication through I2C, SPI, UART or other

We are primarily looking for an IC that does it all. But if TI offers and IC that can meet the Solar Panel and Battery requirements, and another IC that can meet the DC-DC outputs requirements it would be good too.

Thanks  a lot for your support! I hope there is something in your portfolio!

  • HI Juan,

    I am sorry. I don't know of a part that would do these features exactly. Is it possible to break up the rails or requirements?

    First, I would start with why is the host communication channel needed? Is it just for the battery charger? If so you, might be able to just look for a battery charger and a 2 channel PMIC or 2 discretes for the DCDCs.
  • Hello Michael,

    Sorry for my late reply. Since we did not find such a part in the market, we decided to continue our current approach which is breaking the problem in smaller parts.

    Thanks,
