Auto-Balance Supercapacitors with Voltage Ratings of 3V or Higher

Topics Covered

  • Understanding the Importance of Balancing Supercaps Rated 3V or Higher
  • Managing Power Efficiency in Supercap Balancing
  • Optimizing Performance with MOSFET Auto-Balancing Technology
  • Preventing Voltage Runaway in Supercaps
Technical Brief Overview 

Connecting supercapacitors in series can introduce voltage and leakage-current imbalances that reduce reliability and increase the risk of cell damage. This technical brief explains how Advanced Linear Devices’ SAB™ MOSFETs provide active, continuous balancing for series-connected supercapacitors while consuming near-zero power.

The brief also examines the ALD910030 SAB MOSFET, including its voltage regulation characteristics, current response, and use in higher-voltage supercapacitor stacks. Readers will see how automatic balancing can help protect individual cells, improve system stability, and simplify the design of energy storage and backup power applications.
