ALD810026SCL

Special Purpose Overview

The ALD810026SCL is a quad Supercapacitor Auto Balancing (SAB) MOSFET array manufactured by Advanced Linear Devices Inc. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 16-pin SOIC package. The device features a drain-source breakdown voltage of 10.6V, an operating current limit of 80mA, and a power dissipation rating of 500mW. It provides four independent SAB channels with a typical gate threshold voltage of 2.60V at 1µA.

Special Purpose Feature Summary

• Precision factory-trimmed gate threshold voltages for accurate balancing
• Exponential leakage current regulation based on cell voltage
• Near-zero additional leakage currents below rated thresholds
• Integrated active response without external control logic

Special Purpose Applications

• Series-connected supercapacitor cell leakage balancing
• Energy harvesting systems
• Long-term backup battery configurations with supercapacitor outputs
• Zero-power voltage dividers at selected voltages

Special Purpose Procurement Notes

Verify the specific suffix 'L' indicates lead-free RoHS compliance. Confirm the 'SCL' designation corresponds to the 16-pin SOIC package and the commercial 0°C to +70°C operating temperature range. Ensure compatibility with industrial variants if extended temperature operation is required.

Special Purpose Selection Notes

Select this component when balancing up to four series-connected supercapacitors in a single package. Verify that the maximum supercapacitor leakage current aligns with the device's output current capabilities. Consider the industrial SCLI variant if operation below 0°C or above +70°C is necessary.

Special Purpose Part Context

This part belongs to the ALD8100xx family of SAB MOSFET arrays designed for voltage and leakage-current balancing of series-connected supercapacitors. It complements the dual-channel ALD910026 variant and shares core EPAD technology for precise automatic balancing applications.

Special Purpose Replacement Considerations

The ALD810026SCLI serves as the industrial temperature version of this component. For dual-channel requirements, the ALD910026SAL is the corresponding alternative.
