Deskripsi Produk
          Slim BQ4050-Based 4S 5A Lithium Battery BMS BAKTH-ITL0040050019-01 for Portable Devices
The BAKTH-ITL0040050019-01 is a smart battery management system (Smart BMS) specially designed for 4-series (4S) 3.6V/3.7V Li-ion batteries, developed based on TI BQ4050/BQ40Z50 solutions. Featuring a long-strip integrated PCB design, SMBUS communication interface and external NTC temperature probe, this BMS supports bidirectional data interaction, accurate fuel gauge and full-range battery status management. It also features comprehensive safety protection mechanisms, making it an ideal solution for high-reliability scenarios such as pen-style battery packs and portable devices.
   
Core Advantages
  • Full-Suite Safety Protection: Complete protection against overcharge, over-discharge, overcurrent, short circuit, and over-temperature, maximizing battery safety and lifespan.
  • Long Strip Integrated Design for Narrow Battery Compartments: The long-strip PCB is custom-designed for pen-style power banks, elongated energy storage devices, portable lighting and other scenarios. It solves the installation challenges of square BMS in narrow spaces, maximizing internal space utilization. It adopts industrial-grade SMT process for excellent vibration and interference resistance, suitable for harsh operating environments.
  • Cell Balancing for Longer Life: Built-in cell balancing function eliminates cell inconsistency, ensuring each 3S cell charges and discharges uniformly, improving battery pack efficiency and extending its overall service life. 
  • Flexible Customization: Adjustable overcurrent thresholds and OEM/ODM options to match your specific product requirements.
