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
A good PCB layout for the ISL71026MVZ involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the input and output traces. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
To ensure the ISL71026MVZ operates within its recommended operating conditions, monitor the input voltage, output voltage, and operating temperature. Ensure the input voltage is within the recommended range of 3.3V to 5.5V, the output voltage is within the recommended range of 0.8V to 3.3V, and the operating temperature is within the recommended range of -40°C to 125°C.
The recommended input capacitor value for the ISL71026MVZ is 10uF to 22uF, with an X5R or X7R dielectric type. This ensures low ESR and high capacitance, which helps to filter out noise and ripple on the input voltage.
The output voltage of the ISL71026MVZ can be calculated using the following formula: VOUT = VREF x (1 + R1/R2), where VREF is the internal reference voltage (0.8V), R1 is the feedback resistor, and R2 is the divider resistor. The output voltage range is 0.8V to 3.3V.
The maximum output current of the ISL71026MVZ is 2.5A. However, the output current should be derated based on the ambient temperature and the input voltage to ensure reliable operation.
