The SABMBOVP219 is a precision dual over-voltage protection printed circuit board populated with an ALD910019SALI SAB MOSFET IC, designed for voltage balancing of series-connected supercapacitors. It measures 0.6 inches by 1.6 inches and features mounting holes for easy installation. The board has a threshold voltage of 1.90V and provides a clamp current of up to 100mA at voltages above 1.93V, with output current increasing by approximately 3mA per 1mV above threshold. It operates within a temperature range of -40°C to +85°C and is RoHS compliant. The circuitry enables automatic, passive balancing with near-zero power dissipation below the threshold voltage, making it suitable for energy harvesting and battery-powered applications.
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.
