NCV7719DQR2G

Overview

The NCV7719DQR2G is an octal half-bridge driver designed for automotive motion control applications. It features eight independent outputs capable of driving loads in forward, reverse, brake, and high-impedance states. The device operates with a supply voltage range of 5V to 28V and supports logic levels compatible with both 3.3V and 5V systems. Communication is managed via a 16-bit SPI interface that allows daisy-chaining capabilities. Integrated diagnostics include short-circuit protection, open-load detection, undervoltage lockout, overvoltage protection, overcurrent protection, and thermal shutdown.

Feature Summary

• Provides eight independent half-bridge outputs for precise motor control
• Features comprehensive diagnostic monitoring for system reliability
• Supports serial communication through a daisy-chain compatible SPI interface

Applications

• Automotive HVAC flap DC motor control
• Seat adjustment actuator drive circuits
• Sunroof and window regulator motor management
• General automotive motion control systems

Procurement Notes

Verify the specific suffix DQR2G corresponds to the required tape and reel packaging configuration. Confirm that the component meets AEC-Q100 Grade 1 standards for the intended automotive environment. Ensure the ordering information matches the exact manufacturer part number to guarantee correct pinout and electrical characteristics.

Selection Notes

Select this component when an octal configuration is required for multiple actuators within a single package. Consider its integrated diagnostic features for safety-critical automotive applications. Evaluate the SPI interface requirements against the main controller's available ports. Assess the thermal performance needs relative to the exposed pad package design.

Part Context
