10s Battery Pack Monitoring: Balancing: and Comprehensive Protection. 50A Discharge Reference Design


This reference design is ready tested for 10 cells in series battery pack monitoring: balancing and protection for power tools. Power tools increasingly use highly power-dense Li-Ion or Li-Iron phosphate cells based battery packs that need to be protected from explosion due to incorrect charging or discharging. TIDA-00449 also achieves thermal requirements for power tool battery packs when discharging at high continuous current.

  • Battery pack designed for 36 V (10-cell Li-Ion or  Li-Iron phosphate based): 50-A max continuous discharge currentMonitoring of cell voltages: pack current: pack temperatures and protection by controlling charge/discharge FETs and cell balancingHardware protection for overcurrent in discharge: short circuit in discharge: overvoltage and under voltageUltra-small footprint: low on-resistance: low Qg and Qgd FemtoFET MOSFETs on board for passive balancing current up to 150-mA per cellLow quiescence current and ultra-low power state for shipmentOn-board host microcontroller to enable implementation of battery fuel gauging
