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.
