APS13568KLJATR

Overview

The APS13568KLJATR is a linear LED driver IC from Allegro MicroSystems, designed for single-channel non-isolated output applications. It supports an input voltage range of 7V to 24V and delivers a constant output current of up to 150mA per channel. The device features PWM dimming capability and is housed in an 8-SOIC-EP package with an exposed pad for thermal management. It operates within a temperature range of -40°C to 85°C.

Feature Summary

• Linear regulation architecture for precise current control
• Integrated PWM dimming interface for brightness adjustment
• Single-channel non-isolated output configuration
• Exposed pad thermal enhancement for heat dissipation

Applications

• LED lighting modules requiring constant current drive
• Automotive interior illumination systems
• Industrial indicator lighting circuits
• General-purpose low-power LED arrays

Procurement Notes

Verify the specific suffix KLJA against the manufacturer's latest datasheet to confirm pinout and electrical specifications. Ensure compatibility with the target PCB footprint, specifically the 8-SOIC-EP package dimensions. Confirm RoHS compliance status as regulatory requirements may vary by region and production batch. Cross-reference the component with official replacement lists if sourcing availability is constrained.

Selection Notes

Select this component when a simple linear solution is preferred over switching regulators for noise-sensitive applications. The 150mA output current rating suits small to medium LED loads. Consider the thermal performance of the SOIC-EP package relative to the expected ambient temperature and power dissipation. Verify that the input voltage range aligns with the system's power supply rails.
