AN10704: UJA1023 LIN I/O Slave Application Note
Technical guidance for implementing the NXP UJA1023 LIN I/O slave, covering hardware design, switch configurations, diagnostics, and automatic bit rate detection.
Overview
This application note provides detailed technical information for designing LIN slave nodes using the NXP UJA1023. It outlines implementation strategies for automotive I/O applications, including local and remote switch configurations (switch-to-ground and switch-to-battery). The document details hardware design for switch matrices supporting up to 16 switches via 8 I/O pins, diagnostic functions using multiple input thresholds, and automatic bit rate detection for LIN networks up to 20 kbit/s. It also includes recommendations for ESD protection and handling ground shift failures in automotive environments.
Use Cases
- Automotive switch panels
- Seat control modules
- Steering wheel controls
- Door and roof control units
- Sensor and actuator bus interfacing
- Stand-alone LIN controller applications
