NCV7450DB0R2G

Overview

The NCV7450DB0R2G is an automotive-grade system basis chip from onsemi, integrating a Low Dropout (LDO) voltage regulator with a High-Speed Controller Area Network (HS CAN) transceiver. It provides a fixed 5 V output at 250 mA with a typical dropout voltage of 200 mV and a maximum of 400 mV. The device operates within an input voltage range of 6 V to 18 V and features line regulation of 30 mV and load regulation of 50 mV. Packaged in a 16-TSSOP-EP format, it supports surface mount installation and functions reliably across an operating temperature range of -40°C to +125°C.

Feature Summary

• Integrated HS CAN transceiver combined with a 250 mA LDO regulator
• AEC-Q101 qualified for automotive reliability standards
• Fixed 5 V output with low dropout characteristics (200 mV typical)
• Operates over extended industrial temperature range (-40°C to +125°C)

Applications

• Automotive body control modules
• CAN bus network nodes requiring integrated power management
• Electronic control units (ECUs) with strict space constraints

Procurement Notes

Verify the AEC-Q101 qualification status against official onsemi documentation, as local sources may list conflicting grades. Confirm the package type is 16-TSSOP-EP with exposed pad. Ensure the datasheet specifies the exact electrical parameters for the DB0 suffix variant before procurement.

Selection Notes

Select this component when a single IC solution is required for both power regulation and high-speed CAN communication. The 250 mA output current is suitable for powering low-power microcontrollers and sensors directly. Verify that the 6 V to 18 V input range matches the vehicle's battery architecture.

Part Context

This part belongs to the NCV7450 series of system basis chips designed for automotive applications. It consolidates multiple functions into a compact footprint, reducing board space and assembly complexity compared to discrete solutions. The series is engineered to meet stringent automotive electromagnetic compatibility and thermal requirements.

Replacement Considerations

Check for direct pin-to-pin replacements within the NCV7450 family or other onsemi system basis chips with similar CAN and LDO specifications. Verify that any substitute maintains the same AEC-Q101 qualification and 16-TSSOP-EP package dimensions.
