STMicroelectronics provides a recommended PCB layout in their application note AN5046, which includes guidelines for thermal pad connection, copper pouring, and via placement to ensure optimal thermal performance.
STMicroelectronics provides a component selection guide in their application note AN5046, which includes recommendations for bootstrap diodes, bootstrap resistors, and output capacitors based on the specific application requirements.
According to STMicroelectronics' technical support, the maximum allowed voltage on the bootstrap pin (VB) during startup is 7V. Exceeding this voltage may damage the device.
To ensure proper biasing during startup, it's recommended to add a pull-up resistor (e.g., 1kΩ) between the VCC pin and the bootstrap pin (VB) to ensure the bootstrap capacitor is charged correctly.
The recommended operating frequency range for the VNB28N0413TR is 100 kHz to 500 kHz. Operating outside this range may affect the device's performance and efficiency.
