ALD910023SAL

Special Purpose Overview

The ALD910023SAL is a dual Supercapacitor Auto Balancing (SAB™) MOSFET array manufactured by Advanced Linear Devices, Inc. using EPAD® technology. It balances up to two series-connected supercapacitors with a precision gate threshold voltage of 2.30V at an output current of 1µA. The device operates within a supply voltage range of 0V to +15.0V and features a maximum drain-source breakdown voltage of 10.6V. It provides active current ranges from 1000µA and maintains near-zero leakage currents below rated voltages.

Special Purpose Feature Summary

• Automatically regulates and balances leakage currents across series-connected supercapacitors
• Precision factory trimmed for accurate voltage and current characteristics
• Exponential variable resistance adjusts dynamically based on input voltage
• Zero leakage operation when cell voltage drops below the rated threshold

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
• Scaled supercapacitor stacks and arrays

Special Purpose Procurement Notes

Verify that the ordering suffix 'L' confirms lead-free compliance per RoHS standards. Confirm the package type matches the required surface mount configuration. Ensure the operating temperature range aligns with the commercial specification limits. Cross-reference the datasheet version to validate electrical parameters against the specific revision.

Special Purpose Selection Notes

Select this component for applications requiring automatic balancing of two series-connected supercapacitors. The device integrates high-precision trimming to ensure consistent performance without external calibration. Verify that the maximum operating current and power dissipation ratings accommodate the specific stack requirements. Consider the thermal management needs associated with the specified power dissipation limits.

Special Purpose Part Context

This part belongs to the ALD8100xx and ALD9100xx family of SAB™ MOSFETs designed for supercapacitor balancing. The ALD910023 specifically addresses dual-cell configurations, whereas the ALD810023 supports quad-cell setups. Both utilize production-proven EPAD® technology to provide precise voltage and leakage-current balancing capabilities.
