Procurement Notes
Verify the manufacturer designation as MaxLinear, Inc., noting historical Exar branding. Confirm the SOT-23-6 package type and 25mA output specification match your design requirements. Ensure compatibility with PWM dimming signals if used in variable brightness applications. Check for RoHS compliance status in official documentation.
Selection Notes
Select this component when dual-channel linear LED driving is required with PWM dimming support. The SOT-23-6 package suits space-constrained designs. Verify input voltage ranges against system supply rails. Consider thermal performance for continuous operation at 25mA per channel. Compare with single-channel alternatives if only one LED path is needed.
Part Context
This part belongs to MaxLinear's LED driver portfolio, continuing legacy Exar product lines. It serves as a specialized power management IC for lighting applications. The SOT-23-6 form factor aligns with industry standards for compact consumer electronics. MaxLinear maintains support for these components through authorized distribution channels.
Replacement Considerations
SP7121EK-F/TR is listed as a compatible variant with identical electrical specifications. Verify pinout compatibility before substitution. No other direct substitutes are confirmed in public documentation.
