This reference design measures high cell voltage accuracy for 10s to 16s LiFePO4 battery packs. The reference design consists of a high accuracy battery monitor protector, a gas gauge, a secondary protection device and an M0 to help program and communicate with the other devices. The design monitors each cell voltage, pack voltage and pack current to protect the LiFePO4 battery pack against cell overvoltage, cell undervoltage and charge and discharge overcurrent. The gauge accurately predicts the capacity and life of the battery pack. The design adopts high-side N-channel metaloxide semiconductor field-effect transistor (MOSFET) architecture and has strong driving on and off capability.
