NCV7420D23R2G

Drivers, Receivers, Transceivers Overview

The NCV7420D23R2G is a discontinued LIN transceiver from onsemi, designed for in-vehicle networking. It integrates a LIN v2.0/2.1 physical transceiver with a 3.3 V voltage regulator capable of up to 50 mA output current. The device operates within a battery voltage range of 5 V to 26 V and supports transmission rates up to 20 kBaud. It features thermal shutdown, indefinite short-circuit protection, and load dump protection up to 45 V. The component is housed in an SOIC-14 package (CASE 751AP) and is qualified to AEC-Q100 standards.

Drivers, Receivers, Transceivers Feature Summary

• Integrates a 3.3 V voltage regulator with a maximum output current capability of 50 mA for powering external components such as microcontrollers.
• Supports multiple operating states including normal mode, low slope mode, standby mode, and sleep mode to optimize power consumption and communication performance.
• Provides robust protection mechanisms including thermal shutdown, indefinite short-circuit protection on LIN and WAKE pins, and system ESD protection up to ±12 kV.

Drivers, Receivers, Transceivers Applications

• In-vehicle networking for control devices like door locks, mirrors, car seats, and sunroofs.
• Master or slave node implementation in LIN domain class-A multiplex buses.
• Applications requiring low-cost, single-wire serial communication for non-time-critical passenger comfort functions.

Drivers, Receivers, Transceivers Procurement Notes

This specific part number is officially marked as discontinued by the manufacturer. Verification of availability should focus on obsolete stock or alternative sourcing channels rather than standard production lines. Designers must confirm end-of-life status and plan for component obsolescence management strategies given the discontinuation notification.

Drivers, Receivers, Transceivers Selection Notes

Select this component only if legacy compatibility with the 3.3 V regulator version is required. For new designs, consider the EMC/ESD improved versions such as the NCV7420D24R2G which offers enhanced protection characteristics. Ensure the application does not require active procurement support for this discontinued item.

Drivers, Receivers, Transceivers Part Context

The NCV7420 series belongs to onsemi's in-vehicle networking (IVN) transceiver family. This specific variant, NCV7420D23R2G, represents the tape-and-reel packaging option for the 3.3 V regulator version. It utilizes I3T high-voltage technology to co-exist analog and digital functionalities on a single chip, distinguishing it from standard logic families.

Drivers, Receivers, Transceivers Replacement Considerations

The datasheet explicitly lists the NCV7420D24R2G as an EMC/ESD improved replacement for the 3.3 V regulator version. Users should evaluate the NCV7420D24R2G for pin-compatible upgrades offering enhanced transient protection capabilities.
