概要
Description
TJA1441ATK/0Z is an automotive LIN transceiver from NXP (TJA1441 family). It provides the physical-layer interface between a microcontroller and a LIN bus, converting MCU TX/RX signals to LIN bus levels and handling bus wake-up, fault protection, and short/overvoltage protection in automotive environments.
Key points:
- 5V logic supply with LIN bus interface
- TXD/RXD pins for the MCU side and LIN bus pin for the vehicle network
- Wake-up/dominant-recessive signaling, fault indication, and protection features
- Low standby current and robust protection suitable for automotive temps and conditions
- Packaging variant ATK/0Z denotes a specific automotive-grade package (tape & reel) and marking
Typical use:
- Used in automotive body/comfort modules, door modules, and other LIN-networked ECUs.
For exact specifications (pinout, timing, current limits, pin names), electrical characteristics, and the precise packaging details, consult the TJA1441ATK/0Z datasheet from NXP.

Features
I don’t have the exact datasheet for TJA1441ATK/0Z on hand. If it’s an NXP TJA automotive interface IC (CAN/LIN transceiver), typical features would include:
- Automotive supply range (roughly 4.5–5.5 V) with low-power sleep mode
- TXD/RXD interface with fail-safe behavior
- Slew-rate control on bus pins to reduce EMI
- Protection: short-circuit, undervoltage, overtemperature
- Bus fault protection and fault/diagnostic signaling
- ESD protection for I/O and bus pins
For precise, device-specific features and electrical characteristics, please share the datasheet link or allow me to fetch it.

Application
TJA1441ATK/0Z is a LIN transceiver for 12V automotive networks. It is used to interface a microcontroller with the LIN bus in low-cost, low‑speed in‑vehicle communication. Typical applications include automotive body‑electronics nodes such as door control units, power windows and seats, lighting and mirror actuators, HVAC/climate control, and instrument cluster subsystems. It suits any LIN node in passenger cars or light trucks requiring reliable LIN signaling (wake/sleep and standard timing) in automotive environments.
Package
An 8-pin SOIC (SOP-8) package.
