The SABMB223 is a 2-channel supercapacitor auto-balancing PCB with an ALD910023SALI SAB MOSFET installed, designed to balance two series-connected supercapacitors with near-zero power dissipation. It features a compact 0.6 in. by 1.0 in. form factor with mounting holes and a single 8-lead SOIC footprint. The board operates within an industrial temperature range of -40°C to +85°C and is RoHS compliant. It supports cascading with other SABMBXX boards to balance larger supercapacitor stacks. The ALD910023SALI is rated for a maximum reverse bias diode current of 80 mA per MOSFET and includes optional TO277 footprints for external Schottky clamping diodes. The device is designed for use in energy harvesting and battery-powered applications where long-term leakage current balancing is critical.
ALD offers a line of Supercapacitor Auto Balancing Integrated Circuits (IC) as well as SAB and SABOVP (Over-Voltage Protection) Printed Circuit Boards (PCB). The SAB PCBs provide active continuous leakage current regulation and self-balancing of unlimited quantities of stacked series-connected supercapacitors. These products, when used in appropriately designed applications, dissipate near-zero leakage currents, practically eliminating extra power dissipation. Supercapacitors connected in series stacks can be balanced with various combinations of multiple cascaded SABMB or SABMBOVP packages.
