NCV7240BDPR2G

Overview

The NCV7240BDPR2G is an automotive-grade, eight-channel low-side gate driver manufactured by onsemi. It provides a drive capability of up to 600 mA per channel and operates within a supply voltage range of 3.3 V to 5.5 V. The device features 16-bit SPI control for precise output management and includes a dedicated Limp Home Functionality (LHI) pin that enables outputs OUT1 through OUT4 while disabling OUT5 through OUT8. It is housed in a 24-lead SSOP package with fused leads and is qualified under AEC-Q100 standards.

Feature Summary

• Eight-channel low-side driver architecture with individual 600 mA output current capability.
• Integrated 16-bit Serial Peripheral Interface (SPI) for comprehensive digital control and status reporting.
• Dedicated Limp Home Functionality (LHI) pin for prioritized output activation during fault conditions.
• Built-in protection mechanisms including overload current protection and output clamping for inductive loads.

Applications

• Automotive relay actuation systems
• Solenoid control modules
• High-current load switching applications
• Vehicle body control units

Procurement Notes

Verify the specific ordering suffix 'BDPR2G' against official onsemi documentation to confirm the exact reel quantity and tape-and-reel specifications. Ensure compatibility with the required SSOP-24 footprint and verify that the AEC-Q100 qualification meets the target automotive application's reliability standards before finalizing procurement.

Selection Notes

Select this component when an automotive application requires high-current switching for multiple relays or solenoids from a single controller. The integrated SPI interface reduces pin count compared to parallel control methods. Consider the LHI feature if system safety requires maintaining critical functions during partial failures. Ensure the operating temperature range of -40°C to +150°C aligns with the environmental constraints of the installation site.

Part Context

The NCV7240 belongs to onsemi's family of automotive power management ICs designed for robust vehicle electronics. It complements other drivers like the NCV7718 hex half-bridge driver by offering specialized low-side control. The device supports modern automotive architectures requiring efficient, protected, and digitally controllable power distribution for actuators and lighting systems.

Replacement Considerations

Consult official cross-reference data for direct substitutes. Generic low-side drivers may lack the specific 600 mA rating, AEC-Q100 qualification, or the unique Limp Home functionality. Verify pinout compatibility and thermal performance if replacing with devices from other manufacturers.

FAQ

How does the Limp Home Functionality operate?

The dedicated LHI pin allows the user to enable outputs OUT1 through OUT4 while simultaneously disabling outputs OUT5 through OUT8, ensuring critical loads remain active during fault conditions.

What protection features are included for inductive loads?

Each output driver includes an output clamp specifically designed to handle inductive loads and is protected against overload current conditions.
