SP7122BEK-L/TR

Overview

The SP7122BEK-L/TR is a linear LED driver manufactured by MaxLinear, Inc. It features an internal switch and operates in a SOT-23-6 package. The device provides a fixed output current of 15 mA for LED control applications. It utilizes LIN PWM modulation for brightness adjustment. The component is currently classified as obsolete with no active production status.

Feature Summary

• Integrates an internal power switch for direct LED driving
• Supports LIN PWM modulation for precise brightness control
• Delivers a fixed 15 mA output current

Applications

• LED backlighting systems
• Indicator lighting circuits
• General illumination control

Procurement Notes

Verify component obsolescence status before integration. Confirm availability through secondary distributors or surplus channels. Evaluate long-term supply chain stability for production runs. Check RoHS compliance documentation against specific project requirements. Assess lead times from non-standard sources carefully.

Selection Notes

Consider the fixed 15 mA current limit when sizing LEDs. Ensure the application supports LIN PWM signaling for dimming. Verify voltage headroom compatibility with the internal switch topology. Compare pinout and thermal characteristics against alternative drivers if redesign is feasible due to obsolete status.
