Monitoring, balancing and protection of 10-cell battery pack

TI Designs TIDA-00449 is a ready-to-use and tested hardware platform for monitoring, balancing and protecting power tool 10-cell series battery packs. Power tools increasingly use high power density battery packs based on lithium-ion or lithium iron phosphate cells, which require explosion protection against incorrect charging or discharging. TIDA-00449 also meets the thermal requirements for power tool battery packs when discharged at sustained high currents.
