GENERAL DESCRIPTION

The SABMB16 is a 4-channel universal Printed Circuit Board

(PCB) designed to be used with the entire ALD8100XX and

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

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
