ALD810030SCLI

Special Purpose Overview

The ALD810030SCLI is a quad Supercapacitor Auto Balancing (SAB) MOSFET array manufactured by Advanced Linear Devices. It utilizes EPAD technology to balance up to four series-connected supercapacitors. The device features a precision gate threshold voltage of 3.00V at an output current of 1µA, with an operating temperature range of -40°C to +85°C. It operates within a supply voltage of 15.0V and includes 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 'SCLI' confirms the industrial temperature range (-40°C to +85°C) and lead-free (RoHS) compliance as documented in the manufacturer's ordering information. Ensure the component matches the 16-pin SOIC physical package dimensions before integration into the design.

Special Purpose Selection Notes

Select this component when balancing four series-connected supercapacitors is required. The device provides precise automatic balancing without external control circuitry. Consider the ALD910030 family member if only two cells require balancing. Verify that the maximum drain-source voltage rating of 10.6V accommodates the individual supercapacitor voltage limits.

Special Purpose Part Context

This part belongs to the ALD8100xx/ALD9100xx family of SAB MOSFET arrays. These devices are designed specifically for addressing voltage and leakage-current balancing in supercapacitor stacks. They utilize production-proven EPAD CMOS technology to provide high-precision analog performance for energy storage applications.

Special Purpose Replacement Considerations

The ALD910030 serves as a dual-channel alternative for balancing two supercapacitors. Other members of the ALD8100xx family may offer different electrical characteristics for varying balancing requirements.
