Overview
The IS31BL3212-STLS2-TR is a linear LED driver IC manufactured by Lumissil Microsystems. It provides a single constant current output of 23 mA for driving LEDs. The device operates within an input voltage range up to 5.5 V and supports an operating temperature range from -40°C to +85°C. It is housed in a compact SOT-23-6 surface-mount package, designed for efficient space-constrained applications requiring precise LED current regulation.
Feature Summary
- Provides regulated constant current output for stable LED brightness
- Integrates linear drive topology for simplified circuit design
- Supports wide industrial operating temperature range
Applications
- General LED illumination
- Indicator lighting circuits
- Low-power display backlighting
Procurement Notes
Verify the specific suffix STLS2-TR against official Lumissil documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to assembly planning. Ensure the component meets the required thermal dissipation capabilities for the intended enclosure environment.
Selection Notes
Select this component when a single-channel linear LED driver with 23 mA output is required. It is suitable for designs where input voltage exceeds the forward voltage of the LED string but does not necessitate a switching converter. Verify that the SOT-23-6 package fits the PCB footprint constraints and that the thermal performance is adequate for the application's power dissipation requirements.
Part Context
This part belongs to the IS31BL series of LED drivers from Lumissil Microsystems. The series focuses on linear regulation solutions for various LED lighting applications. The BL3212 variant specifically targets single-channel constant current needs, distinguishing itself from multi-channel or boost-topology counterparts within the broader product portfolio.
Replacement Considerations
Check for direct pin-to-pin replacements within the IS31BL family with adjusted current ratings. Verify if alternative manufacturers offer compatible linear LED drivers with similar 23 mA output and SOT-23-6 packaging. Ensure any substitute maintains the same electrical characteristics and thermal limits.
