NCV7718BDQR2G

Overview

The NCV7718BDQR2G is a hex half-bridge driver manufactured by onsemi, designed for stepper motor control applications. It features six independent half-bridge outputs capable of driving up to 0.5A per channel with a maximum collector-emitter voltage of 28V. The device operates within a supply voltage range of 3.15V to 5.25V and supports a wide operating temperature range from -40°C to +125°C. Packaged in a compact SSOP-24 format measuring 8.64mm x 3.9mm x 1.65mm, it is suitable for surface-mount installation.

Feature Summary

• Provides six independent half-bridge output channels for precise stepper motor phase control
• Supports operation across an extended industrial temperature range up to +125°C
• Integrated protection mechanisms ensure reliable performance under varying load conditions

Applications

• Stepper motor drive circuits
• Precision motion control systems
• Industrial automation actuators

Procurement Notes

Verify the specific suffix BDQR2G against official onsemi documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for SSOP-24 packages. Confirm that the 0.5A current rating meets the requirements of the intended stepper motor coils. Check for any automotive qualification certifications if deploying in vehicle environments.

Selection Notes

Select this component when designing low-voltage stepper motor interfaces requiring multiple independent drive channels. The 28V rating provides sufficient headroom for standard 5V or 12V motor systems. Consider the thermal dissipation capabilities of the SSOP package relative to the ambient environment and duty cycle requirements of the application.
