Multi-Cell 36-48V Battery Management System Reference Design

Overview

TopologyOther Topology
IC revisionE2

Description

The TIDA-00792 TI Design provides monitoring, balancing, primary protection and gauging for a 12 to 15 cell lithium-ion or lithium-iron phosphate based batteries. This board is intended to be mounted in an enclosure for industrial systems. The reference design subsystem provides battery protection and gauging configuration with parameters avoiding code development and provides high side protection switching to allow simple PACK- referenced SMBus communication for battery status even while protected.

Features

  • 12- to 15-cell Li-ion and Phosphate BatteryManagement System
  • High-Side Protection Switching Using N-ChannelMOSFETs
  • Cell Balancing for Extended Battery Life
  • Gas Gauging to Estimate System Run Time
  • Subsystem Circuit Design is Tested and IncludesGUI and Getting Started Guide

Remark: BOM and User guide added with main PDF.
