The SABMB221 is a 2-channel supercapacitor auto-balancing PCB with an ALD910021SALI SAB MOSFET pre-installed, designed for balancing two series-connected supercapacitors with near-zero additional power dissipation. The board measures 0.6 in. by 1.0 in. and features an 8-lead SOIC footprint, mounting holes, and terminals labeled V+, A, B, C, and V- for direct connection to supercapacitor nodes. It supports cascading with other SABMBXX boards to balance larger stacks. The ALD910021SALI is rated for industrial temperature range of -40°C to +85°C and RoHS compliance. Optional Schottky rectifiers can be mounted on the board to clamp reverse surge currents. The device is intended for energy harvesting and battery-powered applications requiring long-term voltage balance without significant power loss.
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.
