A good PCB layout for the BQ24251RGER involves placing the IC close to the battery, using a solid ground plane, and keeping the high-current paths short and wide. TI provides a recommended layout in the datasheet and application notes.
TI provides a component selection guide 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 also offers online tools and calculators to help with component selection.
The BQ24251RGER has a thermal shutdown feature that protects the device from overheating. To ensure reliable operation, ensure good airflow, use a heat sink if necessary, and follow TI's thermal design guidelines. The device can operate up to 105°C, but derating may be necessary at high temperatures.
The BQ24251RGER has built-in OVP and UVP features. For OVP, connect the OVP pin to a voltage divider that sets the OVP threshold. For UVP, connect the UVP pin to a voltage divider that sets the UVP threshold. TI provides more details in the datasheet and application notes.
Yes, the BQ24251RGER has a low IQ mode that reduces power consumption when not charging. This mode can be enabled by pulling the EN pin low. In this mode, the device consumes only a few microamperes of current.
