Industrial Precision Products

Intersil’s High-Performance Integrated Analog Solutions

Multi-cell Battery Management (MCB)

  • Intersil’s Li-ion battery pack monitoring, protection, and balancing IC
  • Ideal for packs from 3 to 12 cells, ensures pack safety and long run time
  • Built-in fault detection for open-wire, overvoltage, undervoltage, over-temperature, and cell mismatch. Meets stringent safety standards.
  • Example applications: power tools, generators, lawn mowers, vacuum cleaners, solar (charge, distribution), battery backup (UPS), military (handheld radios), e-bike/e-moto
