ALD910024SAL

Special Purpose Overview

The ALD910024SAL is a dual Supercapacitor Auto Balancing (SAB) MOSFET array manufactured by Advanced Linear Devices. It operates within a supply voltage range of 0V to +15.0V and features a Drain-Source Breakdown Voltage (BVDSX) of 10.6V. The device supports an Operating Current up to 80mA with a Power Dissipation rating of 500mW. It utilizes EPAD technology for precision leakage-current balancing in series-connected supercapacitors, offering a Gate Threshold Voltage (Vt) of 2.40V at IDS(ON) = 1µA. The component is housed in an 8-Pin SOIC package.

Special Purpose Feature Summary

• Automatically regulates and balances leakage currents across series-connected supercapacitors
• Precision factory trimmed gate threshold voltage ensures accurate voltage limiting
• Exponential output current characteristic provides effective variable resistance control
• Near zero additional leakage currents when connected across supercapacitor stacks

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 to confirm the operating temperature range. The 'L' suffix indicates lead-free compliance per RoHS standards. Ensure the required thermal environment aligns with either the commercial (0°C to +70°C) or industrial (-40°C to +85°C) grade specifications before procurement.

Special Purpose Selection Notes

Select this component for applications requiring automatic balancing of two series-connected supercapacitors. The dual-channel configuration simplifies circuit design compared to discrete solutions. Verify that the maximum supercapacitor leakage current limit matches the device's output current capabilities at the desired input voltage threshold.

Special Purpose Part Context

This part belongs to the ALD9100xx family of SAB MOSFET arrays, designed specifically for addressing voltage and leakage-current balancing issues in ultracapacitor stacks. It complements the quad-channel ALD810024 variant, providing a compact solution for lower-capacity energy storage configurations.
