General Description

The ALD810018/ALD910018 are members of the ALD8100xx (quad) and ALD9100xx (dual) family of Supercapacitor Auto Balancing MOSFETs, or SAB™ MOSFETs.

SAB MOSFETs are built with production proven EPAD® technology and are designed to address 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.

Overview

ADVANCED LINEAR DEVICES, INC.

e TM EPAD ® ENAB L E D ALD810018/ALD910018 QUAD/DUAL SUPERCAPACITOR AUTO BALANCING (SAB™) MOSFET ARRAY.

Key Features

a precision gate threshold voltage in the Vt mode, which is 1.80V 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. Different VIN produces an Output Current IOUT = IDS(ON) characteristic 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 vol.
