LED8102SXTTR

Overview

The LED8102SXTTR is an 8-channel linear LED driver IC from STMicroelectronics, housed in a 16-HTSSOP package. It operates on a 3 V to 5.5 V supply and delivers up to 100 mA per channel with a maximum output voltage of 19 V. The device supports PWM dimming via an enable pin and direct switch control for local dimming. It features thermal shutdown protection at approximately 170 °C and ESD protection rated at 2.0 kV HBM.

Feature Summary

• Eight independent low-side constant current channels with programmable output current
• Direct switch input control enabling local dimming and toggle actions
• Global brightness adjustment through a dedicated PWM signal on the output enable pin
• Integrated thermal management that forces shutdown upon overheating

Applications

• LED backlighting systems
• General lighting applications
• RGB LED color control arrays
• Monochromatic LED illumination

Procurement Notes

Verify the specific suffix against official documentation to confirm packaging type and reel specifications. Ensure compatibility with the required operating temperature range and thermal dissipation requirements for the target application. Cross-reference the exact part number with the manufacturer's latest datasheet to confirm active status and compliance certifications.

Selection Notes

Select this component for designs requiring multiple low-current LED channels controlled by simple switches or microcontrollers. It is suitable for applications where linear regulation is acceptable and series LED configurations do not exceed the 19 V limit. Consider the exposed pad package for effective heat dissipation during continuous operation.

Part Context

This part belongs to the LED8102S family of monolithic LED drivers designed for low-voltage operations. It integrates eight regulated current sources into a single compact package, simplifying the design of multi-channel lighting systems without the need for complex external circuitry or additional power stages.

Replacement Considerations

Consult official substitution lists for verified alternatives. Generic cross-references may not match the specific switch control interface or thermal characteristics.
