Advanced Linear Devices Inc. (ALD), a design innovation leader in analog technology, today announced a two-channel supercapacitor automatic balancing (SAB) printed circuit board (PCB) that balances leakage current, manages over-voltage and dissipates zero power. Each SABMB2 balances two supercapacitors used in a series stack. The board is well suited for both prototyping or production, and it is an easy-to-use out-of-the-box solution, with no additional engineering resources required. The SABMB2 boards are used in robotics, utility boxes, critical data protection and battery backup products.
ALD’s SABMB2 two-channel board uses an ALD9100xx dual SAB MOSFET to automatically balance each individual supercapacitor cell in the stack. The board allows system designers and developers to control leakage current and balance voltage in each cell, thus preventing over-voltage damage.
Additionally, the SAB MOSFET’s PCB-balancing technology enables ultra-low power operation.
