This reference design includes three designs for high-voltage Lithium-ion (Li-ion) and lithium iron phosphate (LiFePO₄) battery packs up to 1500V. The individual reference designs combined in this architecture are the battery management unit TIDA-101279, the high-voltage management unit TIDA-010272, and the 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.

• ±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 Controller Area Network (CAN) interface up to 1500V
• Robust daisy-chain communication with data reclocking and ring architecture
• Robust and programmable battery cell and pack protection
