Overview

TopologyBattery Management System
IC revision001

Description

This is a full cell-temperature sensing and high cell voltage accuracy Lithium-ion (Li-ion), lithium iron phosphate (LiFePO4) battery pack (32s) reference design. The design monitors each cell voltage, cell temperature and protects the battery pack to secure safe use. This design uses onboard and offboard daisy-chain communication interface for a cost-effective stacked bus connection. These features make this reference design applicable for high-capacity battery pack applications.

Features

  • ±1.5-mV voltage accuracy at 25°C without calibration
  • Passive cell balancing up to 100 mA using internal MOSFET or external BJT
  • Full cell-temperature sensing with mux
  • Robust and programmable battery cell and system protection
  • Robust daisy-chain communication with data reclocking and ring architecture

Typical applications

  • HD TV
  • Set Top Box, Surveillance systems
  • Industrial Systems
