FAN8702B

Overview

The FAN8702B is a 6-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.

Feature Summary

• Independent 6-channel H-bridge architecture supporting simultaneous motor control
• Integrated constant current and constant voltage drive blocks for precise motor actuation
• Built-in protective mechanisms including short-through protection and thermal shutdown

Applications

• Digital Still Camera (DSC) lens and shutter motor control
• Mobile phone camera autofocus and zoom mechanisms
• Portable imaging devices requiring multi-motor synchronization

Procurement Notes

Verify the exact suffix against official Fairchild Semiconductor documentation to confirm pinout compatibility and electrical specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference datasheet revisions to validate feature availability before integration into design.

Selection Notes

Select this component when designing systems requiring six independent motor channels within a compact form factor. It is suitable for applications needing both constant current and voltage regulation for different motor types. Consider its low saturation voltage and integrated protections for reliable operation in space-constrained portable electronics.

Part Context

This part belongs to the FAN870x series of DSC motor drivers from Fairchild Semiconductor. It complements other variants like the FAN8700 and FAN8705 by offering a specific 6-channel configuration tailored for complex camera modules. The series addresses the need for integrated motor control solutions in consumer imaging hardware.

Replacement Considerations

Official substitutes include the FAN8700 and FAN8705. Verify functional equivalence regarding channel count and drive capabilities. Confirm package compatibility and pin assignments before substitution.
