GENERAL DESCRIPTION The SABMB16 is a 4-channel universal Printed Circuit Board (PCB) designed to be used with the entire ALD8100XX and ALD9100XX family of SAB™ MOSFETs for system designers and application developers. SAB MOSFETs are exclusive EPAD® MOSFETs that address leakage and voltage balance of supercapacitor cells connected in series. Imbalance of leakage currents, although much smaller in magnitude than charging or discharging currents, need to be balanced, as leakage currents are long-term DC values that integrate and accumulate over time. SAB MOSFETs and the SABMB16 boards are compact, economical and effective in balancing any size supercapacitors with little or no additional power dissipation. Each SABMB16 can balance two to four supercapacitors in a series stack. These boards can be cascaded to balance multiple series stacks of up to four supercapacitors each. The SABMB16 is a simple, out-of-the-box plug-and-play PCB solution for development, prototyping, demonstration and evaluation, or production deployment. It is suited for balancing supercapacitor stacks ranging from two in series to hundreds in series, and for supercapacitors of 0.1F to 3000F and beyond. The average additional power dissipation due to use of SABMB boards is zero, which makes this method of supercapacitor balancing very energy efficient. It is especially suited for low loss energy harvesting and long life battery operated applications. Supercapacitors, also known as ultracapacitors, when connected two, three or four cells in series can be balanced with ALD8100XX/ ALD9100XX packages installed on the SABMB16 board. Supercapacitors, when connected more than four cells in series, can be balanced with more than one SABMB16 board (each with ALD8100XX/ALD9100XX packages installed). SABMB16 is a blank PCB, ready for either ALD8100XX or ALD9100XX to be installed. For example, SABMB810025 is a SABMB16 board with one ALD810025SCLI installed and tested. SABMB910025 is a SABMB16 board with two ALD910025SALI installed and tested. These are rated for industrial tempurature of -40°C to +85°C. The SABMB16 board includes the following features for flexibility in a variety of different applications: 1) Two ALD9100XX dual or one ALD8100XX quad SAB MOSFET units installed per board. 2) Two ALD9100XX and one ALD8100XX can be installed on the same SABMB16 board. The two ALD9100XX are connected in series, whereas the ALD8100XX is connected in parallel to the two ALD9100XX units. 3) Optional R1 and R2 resistors can be installed with values ranging from open circuit to 0.0Ω. 4) Optional reverse biased external clamping power diodes (schottky rectifiers) can be installed, on board where necessary, across each SAB MOSFET. 5) Multiple SABMB16 PCBs can be cascaded to form a series chain, paralleling a series-connected chain of supercapacitor cells. 6) Compact size of 0.6 in. by 1.6 in. with mounting holes. 7) Rated for RoHS compatible/industrial temperature range of -40°C to +85°C.
