NCV7429DE5R2G

Overview

The NCV7429DE5R2G is an automotive-grade LIN System Basis Chip manufactured by onsemi. It integrates a LIN transceiver, a 150 mA low-dropout (LDO) regulator, and protection circuits within a single package. The device operates with a supply voltage range of 5 V to 28 V and supports data rates up to 20 kb/s. Designed for harsh environments, it functions between -40°C and +125°C. The component features short-circuit protection and complies with AEC-Q100 standards, making it suitable for robust automotive electronic control units requiring integrated power management and communication capabilities.

Feature Summary

• Integrates LIN transceiver with 150 mA LDO regulator
• Short-circuit protection for output drivers
• Automotive qualified per AEC-Q100 standards

Applications

• Automotive body control modules
• LIN-based sensor nodes
• Actuator control units

Procurement Notes

Verify the specific suffix 'E5' against the official datasheet to confirm pinout and thermal pad configuration. Ensure the ordering part number matches the required tape and reel packaging format. Cross-reference the manufacturer's latest documentation for any obsolescence notices or recommended design-in updates prior to final procurement decisions.

Selection Notes

Select this component when a combined LIN communication interface and regulated power supply are required in a compact form factor. The 150 mA LDO output is suitable for powering low-current peripherals directly from the system basis chip. Consider the SOIC-8 or TSSOP-EP package options based on thermal dissipation requirements and PCB space constraints in the target application design.

Part Context

This part belongs to the NCV7429 series of System Basis Chips designed for automotive applications. It serves as a central node for LIN bus networks, providing both data connectivity and local power regulation. The series is engineered to reduce bill-of-materials count by integrating multiple discrete components into a single reliable semiconductor solution for vehicle electronics.

Replacement Considerations

Check for direct pin-to-pin compatible alternatives within the same family that may offer updated packaging or enhanced current ratings. Verify functional equivalence regarding LDO output current and LIN transceiver sensitivity before substituting.
