Precision MOSFETS Automatically Balance Supercaps in Industrial Apps

Advanced Linear Devices (ALD) has launched a family of Supercapacitor Auto Balancing (SAB) Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) intended for industrial applications to regulate and balance leakage currents while minimizing energy used for balancing supercapacitor cells stacked in series stack of two or more. The MOSFETs are well-suited for a variety of industrial-grade energy storage applications that require an operating temperature between –40° to 85°C. ALD - ALD8100xx


Each device in the industrial SAB MOSFET ALD8100xxx/ALD9100xxx family contains 26 different products, each of which can balance supercapacitors up to four cells in a single IC package. Starting with two cells, the devices can balance an unlimited number of supercapacitor cells stacked in a series. In addition, each device in the SAB MOSFET family dissipates near zero leakage current to eliminate extra power dissipation.


Available in both quad and dual packages, the industrial SAB MOSFETs are made with ALD’s precision EPAD technology. The ALD8100xx/ALD9100xx SAB MOSFET family is available in industry standard 16-L or 8-L SOIC packages. One thousand-piece pricing starts at $1.76 each.
