Bidirectional battery initialization system power board reference design

PMP40182

Overview

This reference design is a battery initialization reference design solution for automotive and battery applications. The module enables a high efficiency single stage conversion for charging and discharging the battery. This design features a 0.1% accurate current control loop using the high performance INA225 current sense amplifier. The design was achieved in a compact form factor (40mmX143mmX20mm).

characteristic

● S.R. buck/boost topology for both charge/discharge
● Extra high efficiency up to 94%
● High current accuracy 0.1% and good linearity
● Discrete solution is easy for re-design
● Interface reserved for MCU control and measurement

EEPROM address problem
EEPROM address problem, if there are 10 24C02s on the bus, how does the MCU or main control identify which EEPROM it corresponds to? I see that many are directly connected in parallel on the bus, and
