ALD810029SCLI

Special Purpose Overview

The ALD810029SCLI is a quad N-channel Supercapacitor Auto Balancing (SAB™) MOSFET array manufactured by Advanced Linear Devices, Inc. It utilizes EPAD® technology to automatically regulate and balance leakage currents in series-connected supercapacitors. The device features a precision factory-trimmed gate threshold voltage of 2.90V 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 gate threshold voltage for accurate balancing
• Exponential variable resistance characteristic based on input voltage
• Near zero additional leakage currents with fast response time

Special Purpose Applications

• Series-connected supercapacitor cell leakage balancing
• Energy harvesting systems
• Long term backup battery with supercapacitor outputs
• Scaled supercapacitor stacks and arrays

Special Purpose Procurement Notes

Verify the specific ordering suffix 'L' indicates lead-free compliance and RoHS adherence. Confirm the operating temperature range corresponds to the industrial grade (-40°C to +85°C). Ensure the package type matches the required 16-pin SOIC configuration for your design.

Special Purpose Selection Notes

Select this component when balancing up to four supercapacitors in series is required. The 2.90V threshold voltage determines the maximum operating voltage per cell. Consider the exponential current-voltage relationship for precise control over leakage dissipation and power management in high-voltage stacks.

Special Purpose Part Context

This part belongs to the ALD8100xx family of SAB™ MOSFETs designed for supercapacitor voltage and leakage-current balancing. It complements the dual-channel ALD9100xx series. Both families utilize production-proven EPAD® technology to provide scalable solutions for managing voltage distribution in energy storage applications.

Special Purpose Replacement Considerations

The ALD910029SALI serves as a dual-channel alternative for balancing two supercapacitors. Verify pinout compatibility and channel count requirements before substitution. Ensure the threshold voltage specifications align with the target supercapacitor voltage limits.
