Overview

This reference design includes three designs for high-voltage Lithium-ion (Li-ion) and lithium iron phosphate (LiFePO4) battery pack up to 1500V. The individual reference designs combined in this solution are battery management unit TIDA-101279, high voltage management unit TIDA-010272, battery control unit TIDA-010253. The design monitors each cell voltage, cell temperature, bus voltage, shunt current, insulation impedance, and protects the battery pack for safe use. These features make this reference design applicable for high-capacity battery pack applications.

Features

±2.4mV cell voltage accuracy at –40°C to 125°C without calibration
±0.5% bus voltage accuracy at 25°C
±10mA at 25°C, < 10A; ±0.1% error at 25°C, > 10A of shunt current
Supports stackable architecture through daisy chain and CAN interface up to 1500V
Robust daisy-chain communication with data reclocking and ring architecture
Robust and programmable battery cell and pack protection
