GENERAL DESCRIPTION
The ALD810017/ALD910017 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.
The ALD810017 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.
The ALD910017 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.
Each SAB MOSFET features a precision gate threshold voltage in
the Vt mode, which is 1.70V when the gate-drain source terminals
(VGS = VDS) are connected together at a drain-source current of
IDS(ON) = 1µA. In this mode, input voltage VIN = VGS = VDS. Dif-
ferent VIN produces an Output Current IOUT = IDS(ON) character-
istic and results in an effective variable resistor that varies in value
exponentially with VIN. This VIN, when connected across each
supercapacitor in a series, balances each supercapacitor to within
its voltage and current limits.
When VIN = 1.70V is applied to an ALD810017/ALD910017, its
IOUT is 1µA. For a 100mV increase in VIN, to 1.80V, IOUT increases
by about tenfold. For an additional increase in VIN to 1.92V for the
ALD910017 (1.94V for the ALD810017), IOUT increases one hun-
dredfold, to 100µA. Conversely, for a 100mV decrease in VIN to
1.60V, IOUT decreases to one tenth of its previous value, to 0.1µA.
Another 100mV decrease in input voltage would reduce IOUT to
0.01µA. Hence, when an ALD810017/ALD910017 SAB MOSFET
is connected across a supercapacitor that charges to less than
1.50V, it would dissipate essentially no power.
