ALD810030SCLI Image

The ALD810030SCLI from Advanced Linear Devices is a Quad Supercapacitor Auto Balancing (SAB) MOSFET Array that is designed to provide voltage spike suppression and leakage-current balancing operations in supercapacitors connected in series. It has a drain-source voltage of up to 10.6 V, a gate threshold voltage of 3.00 V, and a drain-source on-resistance of 26000 Mega-Ohms. This MOSFET has a continuous drain current of less than 80 mA. It uses a combination of four MOSFET devices that are connected across each supercapacitor stack to balance the leakage current and prevent over-voltage events.

This MOSFET array is given a precision gate threshold voltage and exhibits complementary opposing current levels resulting in little additional leakage current, thereby balancing each supercapacitor to within its voltage and current limits. It is available in a surface-mount package that measures 3.5 x 9.80 mm and is ideal for series-connected supercapacitor cell leakage balancing, zero-power voltage divider, matched current mirrors, current sources, scaled supercapacitor stacks and arrays, long-term battery backup, and energy harvesting applications.
