概述

Description

NCV84140DR2G is an automotive-grade CAN transceiver in NXP’s NCV family. It sits between a CAN controller (on the MCU side) and the physical CAN bus (CANH/CANL), translating the controller’s TXD into differential bus signals and converting bus signals back to RXD. It provides robust protection and fault handling for automotive environments, such as overvoltage/undervoltage protection, short-circuit protection on the CAN lines, thermal shutdown, ESD protection, and diagnostic/status outputs. The device is designed for the harsh conditions of automotive electrical systems and typically supports a wide supply range suitable for 12 V networks, with operation specified over automotive temperature ranges. The DR2G suffix denotes a specific RoHS-compliant package variant. For exact pinout, electrical limits, and application notes, refer to the official NCV84140DR2G datasheet.

Features

NCV84140DR2G features (concise):
- Automotive-grade, 4-channel smart high-side switch
- Wide input range: approx 4.5–28 V; supports automotive load-dump
- Independent channel on/off control with per-channel current limit
- Protective functions: overcurrent, short-to-ground, overtemperature, undervoltage
- Open-load detection and diagnostic fault reporting for each channel
- Global fault status with suitable status/diagnostic outputs
- Sleep/standby mode with low quiescent current
- Reverse polarity protection and load-dump protection
- Robust ESD/EMC robustness for automotive environments
- Package: DR2G (compact 8-pin)
Note: Always verify exact specifications in the official datasheet for your exact part/revision.

Package

8-pin SO-8 surface-mount package (RoHS lead-free; DR2G suffix denotes this package).

Pinout

- Pin count: 8 pins (8-pin package, e.g., SOIC/DIP style)
- Function: Automotive single-channel high-side switch with built-in protection (current limit/short-circuit protection and fault/diagnostic feedback). Used to switch a load to Vcc: input/control, enable, output to load, supply (Vcc), and ground (GND) pins.

Manufacturer

- Manufacturer: NXP Semiconductors (NXP).
- What kind of company: A Dutch multinational semiconductor company that designs and manufactures integrated circuits and related electronic components for automotive, industrial, and consumer markets.
