ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended, and the thermal pad should be connected to a ground plane or a dedicated heat sink.
To ensure reliable operation at high temperatures, it's essential to follow the recommended operating conditions, including the maximum junction temperature (Tj) of 150°C. Additionally, consider using a heat sink, and ensure good airflow around the device. ROHM also recommends using a thermistor or thermal sensor to monitor the temperature.
Although the datasheet specifies the recommended operating voltage range, the maximum allowable voltage for the input pins is typically 5.5V. However, it's essential to note that exceeding this voltage may cause damage to the device or affect its reliability.
ROHM recommends using ESD protection devices, such as TVS diodes or ESD arrays, on the input lines to protect the FMG1AT148 from electrostatic discharge. Additionally, follow proper handling and storage procedures to prevent ESD damage.
ROHM recommends storing the FMG1AT148 in a dry, cool place, away from direct sunlight and moisture. The storage temperature should be between -40°C and 125°C, and the humidity should be below 60%. Avoid storing the devices in environments with high temperatures, humidity, or exposure to chemicals.
