NCV7705DQBR2G

Overview

The NCV7705DQBR2G is a dedicated mirror module driver integrated circuit manufactured by onsemi, designed for automotive exterior mirror control applications. It integrates high-side and low-side drivers to actuate motors for mirror positioning, folding, and heating functions. The device operates within a supply voltage range of 4.5 V to 18 V and supports an operating temperature range from -40°C to +150°C. It features a DQFN-24 package with exposed pad for thermal management and holds AEC-Q100 qualification for automotive reliability.

Feature Summary

• Integrates dual half-bridge drivers for precise control of DC motors used in mirror positioning and folding mechanisms.
• Includes dedicated high-current outputs capable of driving resistive heating elements for mirror defogging and deicing.
• Incorporates comprehensive protection features including overcurrent, thermal shutdown, and reverse polarity protection.

Applications

• Automotive exterior side mirror position adjustment systems
• Power-folding mirror actuation circuits
• Heated mirror element drive modules

Procurement Notes

Verify the specific suffix 'R2G' against the manufacturer's current datasheet to confirm RoHS compliance and packaging details. Ensure the ordering part number matches the required tape-and-reel quantity specified in the official documentation. Cross-reference the AEC-Q100 grade requirements with your vehicle's quality standards before finalizing procurement.

Selection Notes

Select this component when designing exterior mirror control units requiring integrated motor and heater driving capabilities in a compact form factor. Consider the DQFN-24 package size constraints and thermal dissipation requirements relative to the expected load currents. Verify that the 18V maximum supply voltage aligns with the target vehicle's electrical system specifications.

Part Context

This component belongs to onsemi's NCV77xx series of body control drivers, specifically tailored for automotive mirror modules. It complements other body control ICs like the NCV7710 door module driver by providing specialized functionality for exterior mirror assemblies. The series focuses on integrating multiple driver channels into single solutions to reduce bill-of-materials complexity.

Replacement Considerations

Consult the official onsemi replacement guide or datasheet revision history for confirmed substitute part numbers. Do not assume pin-to-pin compatibility with generic motor drivers without verifying internal logic and protection thresholds.
