AL8400SE-7

Overview

The AL8400SE-7 is a linear LED driver controller manufactured by Diodes Incorporated, designed for efficient current regulation in lighting applications. It features a low reference voltage of 200mV to minimize power loss across the sense resistor. The device operates within an input voltage range of 2.2V to 18V and supports an output current setting of 150mA when using a 300mΩ sense resistor. It is housed in a compact SOT353 surface-mount package and functions reliably across an operating temperature range of -40°C to 125°C.

Feature Summary

Offers excellent temperature stability for consistent LED performance
Features a low 200mV reference voltage for high efficiency
Provides adjustable linear current control via external sensing

Applications

LED backlighting systems
General LED illumination circuits
Portable lighting devices requiring precise current regulation

Procurement Notes

Verify the specific suffix 'SE-7' against the manufacturer's latest datasheet to confirm pinout and packaging details. Ensure the design accounts for the thermal characteristics of the SOT353 package under maximum load conditions. Cross-reference the required sense resistor value with the target LED current specification to maintain operational accuracy.

Selection Notes

Select this component for applications requiring simple, cost-effective linear regulation with minimal external components. It is suitable where space constraints favor the SOT353 package and where input voltages remain within the specified 2.2V to 18V range. Consider thermal dissipation requirements if operating at higher currents or ambient temperatures.

Part Context

This part belongs to the AL8400 series of linear LED drivers from Diodes Incorporated. These controllers are engineered for versatility in various LED driving topologies. The series emphasizes stability and ease of implementation, making it a common choice for designers seeking reliable current regulation without complex switching circuitry.
