ALD810020/ALD910020
QUAD/DUAL SUPERCAPACITOR AUTO BALANCING (SAB™) MOSFET ARRAY
GENERAL DESCRIPTION
FEATURES & BENEFITS
• Simple and economical to use
• Precision factory trimmed
The ALD810020/ALD910020 are members of the ALD8100xx
(quad) and ALD9100xx (dual) family of Supercapacitor Auto Bal-
ancing MOSFETs, or SAB™ MOSFETs. SAB MOSFETs are built
with production proven EPAD® technology and are designed to ad-
dress voltage and leakage-current balancing of supercapacitors
connected in series. Supercapacitors, also known as ultracapacitors
or supercaps, connected in series can be leakage-current balanced
by using a combination of one or more devices connected across
each supercapacitor stack to prevent over-voltages.
• Automatically regulates and balances leakage currents
• Effective for supercapacitor charge-balancing
• Balances up to 4 supercaps with a single IC package
• Balances 2-cell, 3-cell, 4-cell series-connected supercaps
• Scalable to larger supercap stacks and arrays
• Near zero additional leakage currents
• Zero leakage at 0.3V below rated voltages
• Balances series and/or parallel-connected supercaps
• Leakage currents are exponential function of cell voltages
• Active current ranges from <0.3nA to >1000µA
• Always active, always fast response time
The ALD810020 offers a set of unique, precise operating voltage
and current characteristics for each of four SAB MOSFET devices,
as shown in its Operating Electrical Characteristics table. It can be
used to balance up to four supercapacitors connected in series.
TheALD910020 has its own set of unique precision Operating Elec-
trical Characteristics for each of its two SAB MOSFET devices,
suitable for up to two series-connected supercapacitors.
• Minimizes leakage currents and power dissipation
APPLICATIONS
• Series-connected supercapacitor cell leakage balancing
• Energy harvesting
• Long term backup battery with supercapacitor outputs
• Zero-power voltage divider at selected voltages
• Matched current mirrors and current sources
• Zero-power mode maximum voltage limiter
• Scaled supercapacitor stacks and arrays
Each SAB MOSFET features a precision gate threshold voltage in
the V mode, which is 2.00V when the gate-drain source terminals
t
(V
GS
= V ) are connected together at a drain-source current of
DS

= 1µA. In this mode, input voltage V = V

its voltage and current limits.

APPLYING THE ALD810020/ALD910020:
GENERAL DESCRIPTION (CONT.)
The voltage dependent characteristic of the ALD810020/
ALD910020 on-resistance is effective in controlling excessive volt-
age rise across a supercapacitor when connected across it. In se-
ries-connected supercapacitor stacks, when one supercapacitor
voltage rises, the voltage of the other supercapacitors drops, with
the ones that have the highest leakage currents having the lowest
supercapacitor voltages. The SAB MOSFETs connected across
these supercapacitors would exhibit complementary opposing cur-
rent levels, resulting in little additional leakage currents other than
those caused by the supercapacitors themselves.
1) Select a maximum supercapacitor leakage current limit for any
supercapacitor used in the stack. This is the same as output cur-
rent, I , of theALD810020/ALD910020. Test that each
= I
OUT DS(ON)
supercapacitor leakage current meets this maximum current limit
before use in the stack.
2) Determine whether the input voltage V (V
IN GS
= V ) at that
DS
I
is acceptable for the intended application. This voltage is the
OUT
same voltage as the maximum desired operating voltage of the
supercapacitor. For example, with theALD810020, I = 1000µA
OUT
corresponds to V = 2.52V.
IN
For technical assistance, please contact ALD technical support at
techsupport@aldinc.com.
3) Determine that the operating voltage margin, due to various
tolerances and/or temperature effects, is adequate for the intended
operating environment of the supercapacitor.
