Overview
The FAN5645MPX is a single-output linear LED driver IC from onsemi, designed for single-wire dimming applications. It operates with an input voltage range of 2.7 V to 5.5 V and provides a high-level output current of 20 mA and a low-level output current of 1 mA. The device features switching frequencies of 64 kHz or 77 kHz depending on the specific variant configuration. It includes integrated short circuit protection and over-temperature protection (OTP) to ensure reliable operation. The component is housed in a compact 6-MLP (3x3 mm) package.
Feature Summary
- Supports single-wire dimming control for simplified interface designs
- Integrates short circuit and over-temperature protection mechanisms
- Provides precise linear current regulation for LED brightness control
Applications
- LED backlighting systems
- Indicator lighting circuits
- Single-wire controlled LED arrays
Procurement Notes
Verify the exact switching frequency specification (64 kHz vs 77 kHz) required for your application when sourcing this component. Confirm that the 6-MLP package dimensions align with your PCB layout constraints. Ensure the input voltage supply remains within the 2.7 V to 5.5 V operational range to maintain proper functionality and protection feature activation.
Selection Notes
Select this component for applications requiring simple single-wire dimming control without complex communication protocols. It is suitable for designs needing integrated protection against shorts and thermal overload. Consider the small 3x3 mm footprint if space is limited. Verify that the 20 mA output current meets the LED requirements.
Part Context
This part belongs to onsemi's portfolio of power management and LED driver solutions. It is designed to simplify LED control interfaces by reducing pin counts through single-wire technology. The integration of protection features makes it robust for consumer and industrial lighting applications where reliability is critical.
