Description and Introduction

Isolated 5-V CAN Transceivers The ISO1050 is a galvanically isolated CAN transceiver manufactured by Texas Instruments (TI). Below are the specifications, descriptions, and features based on TI's datasheet:  

### **Specifications:**  
- **Isolation Voltage:** 2500 VRMS (per UL 1577)  
- **Data Rate:** Up to 1 Mbps  
- **Bus Fault Protection:** ±58 V (DC)  
- **Supply Voltage (VCC1):** 4.5 V to 5.5 V (Logic Side)  
- **Supply Voltage (VCC2):** 4.5 V to 5.5 V (Bus Side)  
- **Operating Temperature Range:** –40°C to +125°C  
- **Common-Mode Transient Immunity (CMTI):** >25 kV/µs  
- **ESD Protection:**  
  - ±8 kV (IEC 61000-4-2, Contact Discharge)  
  - ±15 kV (IEC 61000-4-2, Air-Gap Discharge)  
- **Package Options:**  
  - 16-pin SOIC (DW)  

### **Description:**  
The ISO1050 is a high-performance, galvanically isolated Controller Area Network (CAN) transceiver that meets ISO 11898-2 standards. It provides reinforced isolation between the CAN protocol controller and the physical bus, protecting sensitive electronics from high-voltage transients and ground potential differences.  

### **Features:**  
- **Galvanic Isolation:** 2500 VRMS for signal and power isolation.  
- **Fully Compliant with ISO 11898-2:** Supports CAN FD (Flexible Data Rate) up to 5 Mbps.  
- **High Noise Immunity:** Robust against electromagnetic interference (EMI).  
- **Fail-Safe Features:**  
  - Bus dominant timeout (TXD dominant clamping).  
  - Undervoltage lockout (UVLO) on both supply rails.  
- **Low Loop Delay:** Optimized for high-speed CAN communication.  
- **Wide Temperature Range:** Suitable for industrial and automotive applications.  

This information is sourced from Texas Instruments' official documentation for the ISO1050.

Application Scenarios & Design Considerations
