ALD910026SALI

Special Purpose Overview

The ALD910026SALI is a dual N-channel Supercapacitor Auto Balancing (SAB™) MOSFET array manufactured by Advanced Linear Devices, Inc. It utilizes EPAD® technology to balance voltage and leakage current in series-connected supercapacitors. The device features a precision gate threshold voltage of 2.60V at an output current of 1µA. It operates within a supply voltage range up to 15.0V and supports a maximum operating current of 80mA with a power dissipation rating of 500mW. The component is housed in an 8-pin SOIC package and is rated for industrial temperatures ranging from -40°C to +85°C.

Special Purpose Feature Summary

• Automatically regulates and balances leakage currents across series-connected supercapacitors
• Features precision factory-trimmed gate threshold voltages for accurate balancing
• Provides near-zero additional leakage currents when connected across supercapacitors
• Offers exponential variable resistance characteristics based on input voltage

Special Purpose Applications

• Series-connected supercapacitor cell leakage balancing
• Energy harvesting systems
• Long-term backup batteries with supercapacitor outputs
• Zero-power voltage dividers at selected voltages
• Scaled supercapacitor stacks and arrays

Special Purpose Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +85°C). Confirm the package type matches the required PCB footprint. Ensure the application voltage does not exceed the absolute maximum ratings specified in the datasheet. Check for lead-free compliance if RoHS standards are mandatory for the project.

Special Purpose Selection Notes

Select this component for applications requiring automatic balancing of two series-connected supercapacitors. The 2.60V threshold voltage determines the balancing point; ensure this aligns with the target supercapacitor voltage limits. Consider the 80mA maximum operating current and 500mW power dissipation capabilities when designing the thermal management strategy for the circuit.

Special Purpose Part Context

This part belongs to the ALD9100xx family of SAB™ MOSFET arrays, designed specifically for managing voltage distribution in supercapacitor banks. It complements the quad-channel ALD810026 variant. The device integrates precision analog control directly into the MOSFET structure, eliminating the need for external discrete balancing circuits or complex digital control logic.
