Description

The TI Design TIDA-00449 is a ready, tested hardware platform for 10 cells in series Battery Pack Monitoring, Balancing and Protection for Power Tools. Power Tools increasingly uses 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. The TIDA-00449 also achieves thermal requirements for power tool battery packs when discharging at high continuous current.

Features
  • Battery pack designed for 36V (10 cell Li-Ion or  Li-Iron Phosphate based), 50A max continuous discharge current
  • Monitoring of cell voltages, pack current, pack temperatures, protection by controlling charge/discharge FETs and cell balancing
  • Hardware protections for Overcurrent in discharge, Short circuit in discharge, overvoltage and under voltage
  • Ultra-Small footprint, Low On-Resistance, Low Qg and Qgd FemtoFET MOSFETs on board for passive balancing current up to 150mA per cell
  • Low quiescence current, ultra-low power state for shipment
  • On board host microcontroller to enable implementation of Battery fuel gauging
