ALD810019SCL

Overview

The ALD810019SCL is a quad N-channel Supercapacitor Auto Balancing (SAB) MOSFET array manufactured by Advanced Linear Devices. It operates within a commercial temperature range of 0°C to +70°C and utilizes a 16-pin SOIC package. The device features a typical gate threshold voltage of 1.90V at an on-current of 1µA, with a drain-source breakdown voltage of 10.6V. Maximum continuous operating current is rated at 80mA, and power dissipation reaches 500mW.

Procurement Notes

Verify the specific suffix 'L' indicates lead-free compliance when sourcing. Confirm the 'SCL' designation corresponds to the 16-pin SOIC package variant suitable for surface mount applications. Ensure the component meets the required commercial temperature specifications for your intended deployment environment.

Selection Notes

Select this component for applications requiring automatic balancing of up to four series-connected supercapacitors. The device provides precise voltage regulation without external control circuitry. Consider the exponential current-voltage characteristic for efficient energy management in low-power storage systems.

Part Context

This part belongs to the ALD8100xx family of SAB MOSFETs designed specifically for managing voltage distribution across series-connected ultracapacitors. It addresses leakage-current imbalances that typically cause over-voltages in stacked capacitor configurations, ensuring reliable operation in high-capacity energy storage modules.

Replacement Considerations

The ALD810019SCLI serves as the industrial temperature grade replacement for this component. Verify pin compatibility and electrical characteristics before substitution.
