High-Voltage Batteries with First 100-V High-Side FET Driver

High-Voltage Batteries with First 100-V High-Side FET Driver

Texas Instruments introduced the first single-chip 100-V high-side FET driver for high-power lithium-ion battery applications, delivering advanced power protection and control. The bq76200 high-voltage solution efficiently drives high-side N-channel charge and discharge FETs in batteries commonly used in energy storage systems and motor-driven applications, including drones, power tools, e-bikes and more. For more details, see www.ti.com/bq76200-pr.

Key features and benefits of the bq76200:

  • Versatile supply voltage range: Compatible with a variety of battery architectures, capacities and voltage ranges from 8-V to 75-V, with an absolute maximum of 100-V.
  • Advanced-protection FET control: The fast-switching feature minimizes fault response time and disables the discharge FET if a battery has been severely discharged.
  • Quick development time and reduced overhead: The adaptable driver works with small to large power FET arrays by simply scaling the charge-pump capacitor, reducing engineering overhead and speeding development time.
  • High integration and small package size: The bq76200 integrates a high-voltage charge pump and dual FET drivers into one 5-mm by 4.4-mm by 1-mm thin shrink small outline package (TSSOP).
