NCV7420D24G

Drivers, Receivers, Transceivers Overview

The NCV7420D24G is an automotive-grade LIN transceiver manufactured by onsemi, designed to interface between a LIN protocol controller and the physical bus. It integrates a LIN v2.0/2.1 compliant physical transceiver with a 3.3 V voltage regulator capable of supplying up to 50 mA. The device utilizes I3T high-voltage technology to co-exist analog and digital functions on a single chip. It operates within a battery voltage range of 5 V to 26 V and supports transmission rates up to 20 kBaud in normal slope mode or 10 kBaud in low slope mode. The component features thermal shutdown, indefinite short-circuit protection, and load dump protection up to 45 V. It is housed in a 14-pin SOIC package (CASE 751AP) and is qualified to AEC-Q100 standards.

• Provides enhanced EMC compatibility through integrated slope control
• Features robust protection against thermal overload and electrical shorts

Drivers, Receivers, Transceivers Applications

• Automotive door lock systems
• Vehicle mirror adjustment controls
• Seat position regulation modules
• Sunroof and window operation interfaces

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix to confirm the integrated regulator output voltage, as the NCV7420 family includes variants with different voltage outputs. Ensure the selected part matches the required communication speed and EMC performance specifications for the target application. Confirm availability status, as some revisions of this component series may be discontinued.

Drivers, Receivers, Transceivers Selection Notes

Select the NCV7420D24G when a 3.3 V supply rail is required for the connected microcontroller. Choose the normal slope mode for data rates up to 20 kBaud or low slope mode for reduced electromagnetic emissions at lower speeds. Ensure adequate decoupling capacitors are used on the VCC pin to maintain regulator stability under varying load conditions.

Drivers, Receivers, Transceivers Part Context

This component belongs to the NCV7420 family of Local Interconnect Network (LIN) transceivers from onsemi. The family includes versions with either 3.3 V or 5 V regulators, such as the NCV7420D23G and NCV7420D25G. These devices are part of the in-vehicle networking (IVN) portfolio designed for cost-effective multiplexing in automotive applications.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements include other members of the NCV7420 family, specifically the NCV7420D23G for a 3.3 V regulator or the NCV7420D25G for a 5 V regulator. Verify that any substitute maintains the same SOIC-14 package dimensions and AEC-Q100 qualification if automotive reliability is required.
