FAN5646S700X

Overview

The FAN5646S700X is a linear LED driver from onsemi, packaged in an SC-70-5 surface-mount case. It supports a maximum output current of 20mA per channel and accepts PWM dimming signals for brightness control. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates internal programmable algorithms for blinking or breathing effects without processor intervention
• Supports PWM dimming input for precise brightness adjustment
• Compact SC-70-5 package design suitable for space-constrained applications

Applications

• Status indicators in handheld devices
• Battery-powered consumer electronics
• LED backlighting control systems

Procurement Notes

Verify the specific suffix 'S700X' against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the SC-70-5 footprint matches your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component when integrated blinking functionality is required to reduce microcontroller load. It is suitable for low-current LED applications where compact size and simple PWM interface are prioritized over high-power driving capabilities.

Part Context

This part belongs to onsemi's LED driver portfolio, specifically designed for visual indication tasks. It replaces discrete solutions by combining drive circuitry with timing logic in a single small package, streamlining design for portable devices.

Replacement Considerations

Check for direct substitutes within the FAN5646 series or compatible linear LED drivers from other manufacturers that offer identical SC-70-5 packaging and 20mA output capability.
