STMicroelectronics provides a recommended PCB layout in their application note AN2340, which includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
The gate resistor value depends on the specific application, switching frequency, and power requirements. A general guideline is to use a value between 1 ohm and 10 ohms. Consult the application note AN2340 and the datasheet for more information on gate resistor selection.
The maximum allowed voltage on the bootstrap pin (VB) during startup is typically around 6-7V. Exceeding this voltage can damage the internal bootstrap diode. Consult the datasheet and application note AN2340 for more information on startup sequencing and voltage limitations.
To ensure reliable operation at high temperatures, follow the recommended thermal design guidelines, use a suitable heat sink, and ensure good airflow. Additionally, consider using a thermistor or temperature sensor to monitor the device temperature and implement thermal protection if necessary.
The recommended input capacitor value and type depend on the specific application and input voltage. A general guideline is to use a low-ESR ceramic capacitor with a value between 1uF and 10uF. Consult the datasheet and application note AN2340 for more information on input capacitor selection.
