FAN8702

Overview

The FAN8702 is a six-channel digital still camera (DSC) motor driver IC designed for portable equipment. It integrates two constant current drive blocks and four constant voltage drive blocks to manage shutter, auto-focus, iris, and zoom motors. The device features independent H-bridge outputs with up to 600mA per channel, built-in brake functions on specific channels, short-through protection, and thermal shutdown. It operates at low voltages and includes an internal reference voltage.

Feature Summary

• Integrates independent six-channel H-bridge drivers for precise motor control
• Combines constant current and constant voltage drive blocks for versatile actuator support
• Includes built-in brake functionality and short-through protection mechanisms
• Features integrated thermal shutdown and internal reference voltage

Applications

• Digital Still Camera (DSC) systems
• Mobile phone camera modules
• Shutter motor drive circuits
• Auto-focus mechanism control
• Iris and zoom lens actuation

Procurement Notes

Verify the complete part number including suffixes such as MPX to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free designation against the manufacturer's latest documentation. Check for any specific ordering codes that may affect availability or shipping configuration.

Selection Notes

Select this component when designing portable imaging systems requiring multiple synchronized motor controls. It is suitable for applications needing both constant current and voltage regulation within a single package. Consider its low saturation voltage and low operating voltage requirements for battery-powered devices.

Part Context

This component belongs to Fairchild's portfolio of camera motor driver solutions. It is part of the FAN870x series, which includes variants like the FAN8700 and FAN8705. These ICs are engineered specifically for the compact power and control demands of consumer electronics imaging subsystems.

Replacement Considerations

The FAN8705 is a documented five-channel alternative within the same family. Verify pin compatibility and channel count differences before substitution. Other manufacturers offer similar multi-channel drivers, but functional equivalence must be confirmed via datasheet comparison.
