This reference design is a high-cell voltage-accuracy 5s to 7s lithium-ion (Li-ion), lithium iron phosphate (LiFePO4) battery pack design. The design monitors each cell voltage, pack current, cell and metal-oxide semiconductor field-effect transistor (MOSFET) temperature with high accuracy and protects the Li-ion, LiFePO4 battery pack against cell overvoltage, cell undervoltage, overtemperature, charge and discharge overcurrent and discharge short-circuit situations. The product adopts low-side N-channel MOSFET architecture and has strong driving on and off capability. These features make this reference design highly applicable for power tools and vacuum cleaner battery pack applications.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
