NCV7705DQAR2G

Overview

The NCV7705DQAR2G is a mirror-module driver IC manufactured by onsemi, designed for automotive side-view mirror applications. It integrates control functions for mirror positioning, heating, and folding mechanisms within a single integrated circuit. The device operates with a supply voltage range of 3.15 V to 5.25 V and utilizes an SSOP-36 package with an exposed pad for thermal management. It supports SPI communication for configuration and status monitoring, ensuring reliable operation in automotive environments across the specified temperature range.

Feature Summary

• Integrates motor drivers for precise mirror positioning and actuation
• Includes dedicated heating control outputs for defogging and deicing
• Supports folding mechanism control with diagnostic feedback
• Features SPI interface for system integration and status reporting

Applications

• Automotive side-view mirror module control
• Power mirror positioning systems
• Mirror heating and defrosting circuits
• Auto-folding mirror assemblies

Procurement Notes

Verify the exact package type and marking code against the official datasheet before procurement. Confirm that the SSOP-36 variant matches the design requirements. Ensure compatibility with the vehicle's SPI bus protocol and voltage levels. Check for any specific ordering suffixes that may indicate different tape-and-reel quantities or packaging options. Validate the component's AEC-Q100 qualification status if required by the application specification.

Selection Notes

Select this component when a single IC solution is needed for comprehensive mirror module control. It is suitable for designs requiring integrated motor drive, heating control, and folding functionality. Consider the SSOP-36 package size constraints and thermal dissipation needs. Verify that the SPI interface aligns with the host microcontroller's capabilities. Evaluate the power supply requirements to ensure they fall within the 3.15 V to 5.25 V operating range.

Part Context

The NCV7705DQAR2G belongs to onsemi's portfolio of automotive body control ICs. It is part of a family of solutions designed to simplify the implementation of complex mirror modules. This component addresses the trend toward integrated electronics in automotive mirrors, reducing board space and assembly complexity.
