DESIGN GUIDE

16s Battery Pack Reference Design With Low-Side MOSFET Control for Large Capacity Applications

Description

This reference design is a low current consumption and high cell voltage accuracy 16s Lithium-ion (Li-ion), LiFePO4 battery pack. The design monitors each cell voltage, pack current, cell and MOSFET temperature and protects the battery pack to secure safe use. This design uses five pairs of low-side N-channel MOSFETs and allows a larger discharge current. These features make this reference design highly applicable for high-capacity battery pack applications.
