A good PCB layout for the BQ24618RGET involves keeping the high-current paths short and wide, using a solid ground plane, and placing the input capacitors close to the device. TI provides a recommended layout in the datasheet and application notes.
The selection of external components depends on the specific application requirements, such as input voltage, output voltage, and maximum current. TI provides a component selection guide in the datasheet and application notes, and online tools like the TI Power Stage Designer can also be used to aid in component selection.
The BQ24618RGET has a maximum junction temperature of 150°C. To ensure reliable operation, it's essential to provide adequate heat sinking, use a thermal interface material, and follow the recommended PCB layout. TI provides thermal design guidelines in the datasheet and application notes.
The BQ24618RGET has a built-in overcurrent protection feature that can be enabled by connecting the OCP pin to a resistor divider network. Short-circuit protection can be implemented using an external current sense resistor and a comparator or a dedicated short-circuit protection IC.
The BQ24618RGET is designed to meet EMI and EMC regulatory standards, but proper PCB layout, component selection, and shielding are still essential to ensure compliance. TI provides EMI and EMC guidelines in the datasheet and application notes, and online tools like the TI EMC Simulator can aid in design and compliance.
