STMicroelectronics provides a recommended PCB layout in the application note AN4553, which includes guidelines for component placement, thermal management, and routing to ensure optimal performance and minimize electromagnetic interference (EMI).
The selection of external components, such as the bootstrap capacitor, input capacitor, and output inductor, depends on the specific application requirements and operating conditions. STMicroelectronics provides a component selection guide in the application note AN4553, which includes formulas and guidelines for selecting the correct components.
The maximum junction temperature (Tj) for the BD236 is 150°C, as specified in the datasheet. However, it's recommended to keep the junction temperature below 125°C for optimal reliability and performance.
The BD236 has a built-in overcurrent protection feature that can be enabled by connecting a resistor between the OCP pin and the GND pin. The value of the resistor determines the overcurrent threshold. STMicroelectronics provides more information on implementing overcurrent protection in the application note AN4553.
The recommended input voltage range for the BD236 is 8V to 28V, although the device can operate with input voltages as low as 6V and as high as 32V. However, operating outside the recommended range may affect performance and reliability.
