ALD910017SAL

Special Purpose Overview

The ALD910017SAL is a dual-channel Supercapacitor Auto Balancing (SAB™) MOSFET array manufactured by Advanced Linear Devices Inc. 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 and provides precision gate threshold voltages (Vt) typically at 1.70V when IDS(ON) equals 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
• Features precision factory-trimmed gate threshold voltages for accurate balancing
• Provides near-zero additional leakage currents, effectively acting as variable resistors
• Always active with fast response time to prevent over-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 against manufacturer documentation to confirm temperature range and lead-free status. The 'L' suffix indicates compliance with RoHS standards. Confirm that the commercial grade (0°C to +70°C) meets your operational requirements, or select the industrial variant if extended temperature performance is necessary. Ensure static control procedures are followed during handling due to ESD sensitivity.

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 resistor networks. Consider the exponential relationship between input voltage and output current when determining the maximum allowable leakage current limit for your specific supercapacitor stack. Verify that the 10.6V breakdown voltage aligns with your system's maximum cell voltage.

Special Purpose Part Context

This part belongs to the ALD9100xx family of dual SAB MOSFET arrays, designed alongside the quad-channel ALD8100xx series. Both families utilize production-proven EPAD® technology to address voltage and leakage-current balancing challenges in ultracapacitor stacks. The ALD910017 specifically targets two-cell configurations, offering unique precision operating characteristics tailored for compact energy storage solutions.

Special Purpose Replacement Considerations

The ALD910017SALI serves as the industrial temperature range (-40°C to +85°C) equivalent of the ALD910017SAL.
