NCV7718CDPR2G

Overview

The NCV7718CDPR2G is a Hex Half-Bridge Driver designed for automotive and industrial motion control applications. It features six independent half-bridge drivers controlled via a 16-bit SPI interface, which is daisy-chain compatible. The device supports forward, reverse, brake, and high impedance states with integrated freewheeling protection for both high-side and low-side outputs. Key electrical parameters include a peak current capability of 0.55 A, a typical RDS(on) of 1 Ω, and operation with supply voltages compliant with 5 V and 3.3 V systems. It includes undervoltage and overvoltage lockout, discriminated fault reporting, and a low quiescent current sleep mode.

Feature Summary

• Six independent half-bridge drivers with integrated high-side and low-side freewheeling protection
• 16-bit SPI control interface with daisy-chain compatibility and frame error detection
• Discriminated fault reporting for diagnostics including short circuit, open load, and thermal shutdown
• Low quiescent current sleep mode for energy efficiency in standby conditions

Applications

• Automotive HVAC flap DC motor control
• Industrial motion control systems
• Automotive mirror module driver ICs
• Electromechanical actuator driving

Procurement Notes

Verify the component status as NRND (Not Recommended for New Designs) before procurement. Confirm that the SSOP-24 package matches the target PCB footprint. Ensure the design accounts for the specific SPI timing requirements and diagnostic pin configurations. Validate that the 0.55 A peak current rating meets the load requirements. Check for any specific ordering suffixes or tape-and-reel specifications required by the supplier.

Selection Notes

Select this component when a hex half-bridge configuration is required for automotive-grade motion control. It is suitable for applications needing independent control of multiple motors or actuators with detailed fault diagnostics. Consider the 1 Ω RDS(on) and 0.55 A peak current limits for thermal management. The SPI interface makes it ideal for systems requiring digital control and status feedback. Ensure compatibility with 3.3 V and 5 V logic levels.
