Description:The ISL71026M is a radiation tolerant 3. 3V CAN transceiver that is compatible with the ISO11898-2 standard for applications calling for Controller Area Network (CAN) serial communication in satellites and aerospace communications and telemetry data processing in harsh industrial environments. The transceiver can transmit and receive at bus speeds of up to 1Mbps. The device is designed to operate across a common-mode range of -7V to +12V with a maximum of 120 nodes. The device has three discrete selectable
Renesas provides a recommended PCB layout guide in their application note AN1995, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize noise.
To ensure reliable operation in high-temperature environments, it's essential to follow the recommended thermal management guidelines, including using a heat sink, thermal interface material, and ensuring good airflow. Additionally, the device should be operated within its specified temperature range and derated accordingly.
Renesas recommends using low-ESR ceramic capacitors with a value of 10uF to 22uF for the input and output capacitors. The specific capacitor values and types may vary depending on the application and operating conditions.
To troubleshoot common issues like oscillation or instability, check the PCB layout, component values, and operating conditions. Ensure that the device is operated within its specified voltage and current ranges, and that the input and output capacitors are properly selected. Additionally, use oscilloscopes and other diagnostic tools to identify and isolate the root cause of the issue.
The ISL71026MVZ-T7A is designed to be radiation-hardened and latch-up immune, with a total dose radiation tolerance of up to 100krad(Si) and a latch-up immunity of up to 100mA. However, the specific radiation hardness and latch-up immunity may vary depending on the application and operating conditions.
