TPS65219: Seeking Confirmation: Using BQ24072 + TPS65219 for Powering AM2434-based Design

Tool/software:

Hello everyone,

I'm currently working on a design that uses the AM2434 Sitara microcontroller from Texas Instruments, and I'm in the process of finalizing the power management architecture. In our existing design, we are using the LTC3566 as an all-in-one PMIC solution — it provides both power regulation and battery management functionalities. However, as our system's power requirements are increasing (approximately 2A total system load current), we're evaluating more scalable options.

In the updated design, I'm considering the following approach:

• Use the BQ24072 to handle battery charging (via USB or external DC source), power path management, and automatic switching between external input and battery power.

• Use the TPS65219 PMIC to generate the multiple power rails required by the AM2434 (e.g., 1.1V, 1.8V, 3.3V), leveraging its integrated DC-DC converters and LDOs.

The idea is to use the BQ24072's OUT pin to supply power to the VIN pin of the TPS65219, which would then regulate and distribute the appropriate voltages to the AM2434 and associated peripherals.

This setup appears to meet our requirements, but before finalizing the design, need confirmation 

• Does this combination of BQ24072 + TPS65219 make sense for a system with a ~2A load current and power sequencing needs typical of the AM2434?

• Are there any known limitations or integration challenges between these two ICs that I should be aware of?

• Would you recommend any alternative PMIC + charger combinations that might offer better integration or performance for this use case?

Any insights, suggestions, or confirmation from others who have worked with similar setups would be greatly appreciated.

Thanks in advance!
