ALD810023SCLI

Special Purpose Overview

The ALD810023SCLI is a quad N-channel Supercapacitor Auto Balancing (SAB™) MOSFET array manufactured by Advanced Linear Devices, Inc. It utilizes EPAD® technology to balance voltage and leakage current across up to four series-connected supercapacitors. The device features a precision gate threshold voltage of 2.30V at an output current of 1µA. It operates within a temperature range of -40°C to +85°C and is housed in a 16-pin SOIC package.

Special Purpose Feature Summary

• Automatically regulates and balances leakage currents across series-connected supercapacitors
• Precision factory trimmed for accurate voltage balancing
• Exponential variable resistance characteristic based on input voltage
• Near zero additional leakage currents below rated voltages

Special Purpose Applications

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

Special Purpose Procurement Notes

Verify the specific ordering suffix 'L' indicates lead-free compliance per RoHS standards. Confirm the 'I' suffix corresponds to the industrial operating temperature range of -40°C to +85°C. Ensure the 16-pin SOIC package matches the design requirements. Cross-reference the datasheet version to confirm electrical characteristics remain consistent with the intended application parameters.

Special Purpose Selection Notes

Select this component when balancing up to four supercapacitors in a series stack. The 2.30V threshold voltage determines the maximum operating voltage for each capacitor cell. Verify that the required output current ranges from 0.0001µA to 1000µA align with the supercapacitor leakage specifications. Consider the 10.6V drain-source breakdown voltage limit for the circuit design.

Special Purpose Part Context

This part belongs to the ALD8100xx family of SAB™ MOSFET arrays designed for automatic supercapacitor balancing. It shares core functionality with the dual-channel ALD910023 but provides four independent channels in a single package. The technology relies on production-proven EPAD® processes to achieve high precision without external control circuits.

Special Purpose Replacement Considerations

ALD810023SAL is the commercial temperature variant of the same quad configuration.
