The SABMBOVP229 is a dual-channel over-voltage protection printed circuit board populated with an ALD910029SALI supercapacitor auto-balancing MOSFET, designed for precision voltage clamping in series-connected supercapacitor stacks. The board measures 0.6 in by 1.6 in with mounting holes and operates within an industrial temperature range of -40°C to +85°C. It provides a threshold voltage of 2.90V, with output current increasing sharply from under 100 nA below 2.80V to approximately 100 mA at 2.93V, enabling automatic balancing of capacitance and leakage imbalances. The circuitry can be cascaded with other SABMBOVP2XX boards to support stacks of multiple cells, and includes optional footprints for external Schottky rectifiers to handle transient reverse currents. The board is RoHS compliant and designed for low-power energy harvesting and battery-operated applications where minimal power dissipation 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 SABOVP PCBs provide voltage balancing of series-connected supercapacitors through superior over-voltage clamping circuitry. 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.
