Texas Instruments provides a recommended PCB layout in the datasheet, but it's also recommended to follow general guidelines for high-frequency switching converters, such as keeping the power stage components close together, using a solid ground plane, and minimizing trace lengths and widths.
The selection of the inductor depends on the specific application requirements, such as the input voltage, output voltage, and output current. Texas Instruments provides a list of recommended inductors in the datasheet, but it's also recommended to consult with inductor manufacturers and consider factors such as inductor core material, size, and saturation current.
The BQ24751BRHDR is rated for operation up to 105°C ambient temperature, but the actual maximum temperature may be limited by the specific application and the thermal design of the system. It's recommended to consult with Texas Instruments or a thermal expert to determine the maximum ambient temperature for reliable operation in a specific design.
The BQ24751BRHDR has built-in OVP and UVP features, but the specific implementation details may vary depending on the application. It's recommended to consult the datasheet and application notes for guidance on implementing OVP and UVP, and to consider using external components such as voltage supervisors or comparators to enhance protection.
The recommended input capacitor type and value depend on the specific application requirements, such as the input voltage and frequency. Texas Instruments recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, but it's also recommended to consult with capacitor manufacturers and consider factors such as capacitor size, voltage rating, and temperature rating.
