SABMB910027

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.
