NCV7518MWATXG

Overview

The NCV7518MWATXG is a six-channel low-side gate driver designed for automotive applications. It features an integrated frame error detection mechanism and an open-drain fault flag output to enhance system reliability. The device operates within a supply voltage range of 4.75 V to 5.25 V and supports output voltages of 3.3 V and 5 V. It provides six independent drivers with a maximum output current of 26.5 mA per channel. Propagation delay is specified at a maximum of 2 µs, with rise and fall times of 277 ns each. The component is qualified to AEC-Q100 standards and functions reliably across an operating temperature range from -40°C to +150°C.

Feature Summary

• Integrates frame error detection functionality to monitor signal integrity and ensure robust operation in demanding environments.
• Provides an open-drain fault flag output to facilitate immediate system response to internal or external anomalies.
• Delivers six independent low-side channels capable of driving multiple loads simultaneously with consistent performance.

Applications

• Automotive power distribution systems requiring reliable multi-channel switching
• Smart fuse architectures utilizing electronic protection mechanisms
• General-purpose low-side load driving in vehicle electronic control units

Procurement Notes

Verify the specific ordering suffix to confirm the exact packaging configuration, such as cut tape or reel quantities, as these details impact handling procedures. Ensure that the procurement source provides valid traceability documentation compliant with automotive industry standards. Cross-reference the manufacturer's part number against official distributor catalogs to avoid counterfeit components. Confirm that the delivered units match the specified AEC-Q100 qualification level required for your application.

Selection Notes

Select this component when a high-reliability, multi-channel low-side driver is required for automotive environments. It is suitable for designs needing integrated fault monitoring via frame error detection rather than simple overcurrent protection. Consider the 26.5 mA output current capability to ensure it meets the drive requirements of the target MOSFETs or IGBTs. Verify that the 4.75 V to 5.25 V supply voltage aligns with the system's logic levels and power architecture.
