4-CHANNEL SUPERCAPACITOR AUTO BALANCING PCB
GENERAL DESCRIPTION
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 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
The SABMB16 board includes the following features for flexibility
in a variety of different applications:
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.
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.
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.
MECHANICAL DRAWING
Supercapacitors, also known as ultracapacitors, when connected
two, three or four cells in series can be balanced withALD8100XX/
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).
