BD6757KN-E2

Overview

The BD6757KN-E2 is a 7-channel system lens driver IC designed for digital still cameras and single-lens reflex cameras. It integrates drivers for two DC brush motors, one bipolar stepper motor, and four auxiliary channels within a 52-pin VQCCN package. The device operates on a rated power supply voltage of 3V with a maximum output current of 0.8A per channel. It functions as a stepper motor controller utilizing PWM current drive technology.

Feature Summary

• Integrates seven independent drive channels to manage camera lens mechanisms including DC and stepper motors
• Utilizes PWM current control for precise bipolar stepper motor operation
• Designed specifically for compact digital imaging systems requiring low power consumption

Applications

• Digital still camera lens actuation systems
• Single-lens reflex (SLR) camera autofocus mechanisms
• Compact optical zoom module control circuits

Procurement Notes

Verify the specific suffix E2 against the manufacturer's official documentation to confirm lead-free compliance and RoHS status. Ensure the ordering part number matches the exact package variant required for your PCB layout. Cross-reference the component date code and manufacturing origin with authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component when designing camera modules requiring integrated multi-motor control in a small footprint. Consider the 52-pin QFN package dimensions and thermal dissipation requirements during PCB layout. Verify that the system voltage range aligns with the specified 3V operation and that the peak current demands do not exceed the 0.8A limit per channel.

Part Context

This component belongs to ROHM Semiconductor's line of signal circuit ICs tailored for consumer electronics.
