The SABMB227 is a 2-channel supercapacitor auto-balancing PCB with an ALD910027SALI SAB MOSFET installed, designed to balance two series-connected supercapacitors with near-zero power dissipation. The board measures 0.6 in. by 1.0 in. and features an 8-lead SOIC footprint with mounting holes. It is rated for industrial temperature operation from -40°C to +85°C and complies with RoHS standards. The PCB supports cascading with other SABMBXX boards to balance longer supercapacitor stacks and includes optional TO277 footprints for external Schottky rectifiers to clamp transient reverse currents. The ALD910027SALI device is rated for maximum 80 mA reverse bias current per SAB MOSFET and operates with a maximum 15.0V voltage limit across the chip.
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.
