Maxim provides a recommended PCB layout in the application note AN5141, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The junction temperature can be calculated using the formula: Tj = (DOUT x VREF) / (RSENSE x β), where DOUT is the digital output, VREF is the reference voltage, RSENSE is the sense resistor value, and β is the thermistor beta value. See the datasheet for more details.
The recommended sense resistor value is 1 kΩ to 10 kΩ, depending on the application and desired accuracy. A higher sense resistor value provides better accuracy but increases the measurement time.
While the MAX9060EUK+T is specified for operation up to 150°C, it can be used in high-temperature applications with some limitations. However, the accuracy and reliability may degrade above 150°C. Consult with Maxim's technical support for specific guidance.
To minimize EMI and EMC issues, use proper PCB layout techniques, such as separating analog and digital signals, using ground planes, and adding EMI filters. Additionally, ensure that the MAX9060EUK+T is properly shielded and decoupled.
