The SABMBOVP222 is a precision dual over-voltage protection printed circuit board with one installed ALD910022SALI SAB MOSFET IC, designed for balancing series-connected supercapacitors. The board measures 0.6 in by 1.6 in and features two matched OVP circuits, each with a clamp threshold voltage of 2.20V. It provides a clamp current of up to 100 mA when the input voltage exceeds the threshold by 30 mV, with output current increasing by approximately 3 mA per 1 mV input voltage rise above threshold. The circuit demonstrates a current gain exceeding one million within a 100 mV transition. The board is RoHS compliant and rated for operation from -40°C to +85°C. Mounting holes are provided for secure installation. Two output channels allow simultaneous balancing of two supercapacitor cells, with cascading support for multi-cell stacks.
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.
