SABMBOVP/SABMBOVP2XX

PRECISION DUAL SAB^TMOVER VOLTAGE PROTECTION PCB

FEATURES & BENEFITS

GENERAL DESCRIPTION

• Extremely low output currents at input voltages below the

threshold voltage

• Precision threshold voltage set point

• Extreme change of output current in response to small

changes in input voltage, i.e. dI/dV = ~3mA/1mV

• High maximum clamp output current of 100 mA or greater

• Over Voltage Protection for any size of supercapacitor stacks

in series or in parallel

ALD's SABMBOVP2XX family of Over Voltage Protection Printed

Circuit Boards (PCB) are innovative circuits designed to provide

precision Over Voltage Protection (OVP) in stacked supercapacitor

voltage balancing and other voltage clamping applications. The

SABMBOVP2XX circuit can be viewed as a precision voltage clamp

circuit that offers a superior zener-diode type of functionality and

performs to superior specification and characteristics in creating a

strong, precision voltage clamp. Typically, the clamp current

changes from a few nA to over 100mA (about 1,000,000 times) at

the clamp voltage within a 100mV transition.

• Ultra-low power for energy harvesting and battery-powered

applications

• Fully automatic OVP - no trimming adjustments, no additional

circuits and no software

• Broad selection of threshold voltages for wide variety of OVP

applications

• Corrects imbalances in both capacitance value and DC leakage

current

The SABMBOVP2XX PCB is populated with an ALD9100XX

Supercapacitor Auto Balancing (SAB™) MOSFET IC chip that

specifies the circuit threshold or clamping voltage. SAB MOSFETs

areALD exclusive EPAD MOSFETs designed to address voltage

balancing of multiple supercapacitor cells connected in series. SAB

MOSFETs and the SABMBOVP2XX boards are designed to be

compact, economical and effective in balancing any size

supercapacitors with little or no additional power dissipation.

MECHANICAL DRAWING

The SABMBOVP is a blank PCB designed to be used with the

entire ALD9100XX family of SAB MOSFETs for system designers

and application developers. The SABMBOVP contains two OVP

circuits, each functioning as a precision voltage clamp with

extremely high current gain characteristics. Inside each of two

SABMBOVP circuits on the PCB, the internal voltages of the circuit

are shifted so that the balancing output current from the SAB

MOSFET is amplified to produce nominally 1mA of balancing

SABMBOVP

V+

(clamp) output current at V equal to the rated SAB MOSFET

threshold voltage.

RP4

RP2

The SABMBOVP board’s two circuits function as a pair of push-

pull matched OVP circuits to balance supercapacitors connected

in series. Each OVP circuit can also be used individually with any

electronic circuitry requiring precision over-voltage clamps. The two

OVP circuits offer a very energy efficient solution that can be applied

to other low-loss energy harvesting and long-life battery operated

applications. They can also be connected in cascade mode,

resulting in a single OVP circuit with twice the clamp voltage.
