The SABMBOVP223 is a dual-channel over-voltage protection PCB pre-populated with an ALD910023SALI SAB MOSFET IC, designed for precision voltage clamping and balancing of series-connected supercapacitors. It has a compact size of 0.6 in by 1.6 in with mounting holes and operates over an industrial temperature range of -40°C to +85°C. The circuit provides a threshold voltage of 2.30V, with output current increasing sharply from less than 0.1 µA below threshold to approximately 100 mA at 2.33V, enabling efficient automatic balancing with near-zero power dissipation below the clamp point. It is RoHS compliant and supports cascading multiple boards for higher voltage stacks. Reverse bias protection is available via optional external Schottky diodes.
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.
