NCV7748D2R2G

Overview

The NCV7748D2R2G is a single-channel, low-side power switch with an integrated LIN transceiver, manufactured by onsemi. It operates within a supply voltage range of 2.3V to 5.5V for the load and up to 38V for the Vcc supply. The device delivers a maximum output current of 1.3A and features typical on-resistance values of 800 milliohms and 1.5 ohms. Packaged in a 14-SOIC (0.154 inch, 3.90mm wide) surface-mount enclosure, it supports an operating temperature range from -40°C to +150°C TJ. Certified under AEC-Q100 automotive standards, it includes sleep mode functionality and protection against overcurrent and overtemperature conditions.

Feature Summary

• Integrates a LIN transceiver with a low-side power driver for simplified network connectivity
• Provides overcurrent and overtemperature fault protection mechanisms
• Supports energy-efficient operation through a dedicated sleep mode

Applications

• Automotive body control modules requiring LIN bus connectivity
• Low-side switching applications in vehicle lighting systems
• Actuator control circuits in automotive environments

Procurement Notes

Verify the specific suffix D2R2G against official datasheets to confirm package dimensions and tape/reel specifications. Ensure compatibility with automotive environmental requirements by checking AEC-Q100 certification status. Confirm thermal management needs given the 150°C junction temperature rating. Validate that the 1.3A output current meets system load demands without exceeding thermal limits.

Selection Notes

Select this component when a combined LIN interface and power switching capability is required in a compact SOIC package. Consider the 1.3A current limit and low on-resistance for efficient load driving. Evaluate the 38V Vcc tolerance for robustness against automotive transient voltages. Compare against standard switches if LIN integration is unnecessary to optimize cost and pin count.

Part Context

This part belongs to the NCV7748 family of single-channel low-side drivers with LIN transceivers. It is designed for automotive body electronics where space constraints and wiring complexity necessitate integrated communication and power solutions. The series targets applications demanding high reliability and compliance with strict automotive quality standards.

Replacement Considerations

Consult official substitution lists for equivalent single-channel LIN drivers. Verify pinout compatibility and electrical parameters such as on-resistance and current capacity before replacing.
