Key Document
Description
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).
Features
- 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
