LM5170-Q1: LM5170-Q1 is used in two battery system

Other Parts Discussed in Thread: LM5170-Q1

Hi

Customer want to use LM5170-Q1 in a new project.

The high voltage side is voltage range of 20V~30V, the low voltage side is battery 12.6V (voltage range from 10V to 14V)

There are 2 batteries in this system, they want to control separately.

Can they configure this system as below figure?

LM5107-Q fault detection is disable, Back-Back MOSFETs are controlled by MCU.

When direction from high voltage side to low voltage side, buck1 and buck2 are on, Back-Back MOSFET 1 is turned off by MCU, does this work?

When direction from low voltage side to high voltage side, boost1 and boost2 are on, Back-Back MOSFET 1 is turned off by MCU, does this work?
