APS13568ELJATR

Overview

The Allegro MicroSystems APS13568ELJATR is a single-output linear LED driver IC designed for automotive and industrial applications. It supports a supply voltage range of 7V to 24V and delivers a maximum output current of 150mA per channel. The device integrates internal switching capabilities and features PWM dimming control alongside linear regulation. It operates within an ambient temperature range of -40°C to 85°C and is housed in an 8-SOIC package with an exposed pad (EP) for enhanced thermal performance.

Feature Summary

• Integrates linear regulation with PWM dimming capability for precise LED brightness control
• Features an internal switch structure within a compact surface-mount package
• Designed for robust operation across extended automotive-grade temperature ranges

Applications

• Automotive exterior lighting systems
• Industrial LED illumination modules
• General-purpose constant current LED driving circuits

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels, as the part status is listed as End-of-Life. Confirm that the specific suffix ELJA matches the required pinout and thermal specifications for your PCB layout. Ensure compliance with RoHS3 standards if environmental regulations apply to your assembly process.

Selection Notes

Select this component when a simple linear solution with PWM dimming is preferred over complex switching regulators. It is suitable for low-to-medium power LED strings where efficiency losses are acceptable in exchange for design simplicity. Verify that the 150mA output current aligns with the target LED forward current requirements and that the SOIC-EP package fits the available board space.

Part Context

This device belongs to the APS135 series from Allegro MicroSystems, which focuses on integrated LED drivers for automotive and general lighting markets. The series emphasizes ease of implementation and reliability in harsh environments. The APS13568 variant specifically targets applications requiring moderate current drive with integrated dimming functionality.

Replacement Considerations

The APS13568KLJATR is documented as a parametrically equivalent substitute by the manufacturer.
