A good PCB layout for the BQ25713BRSNR involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. TI provides a recommended layout in the datasheet and application notes.
To select the right inductor for the BQ25713BRSNR, consider the maximum current rating, inductance value, and DC resistance. A good starting point is to use an inductor with a saturation current rating above the maximum output current, and an inductance value between 1-10uH. TI provides a list of recommended inductors in the datasheet.
The BQ25713BRSNR has an operating ambient temperature range of -40°C to 85°C. However, the device can be derated for higher temperatures, and the maximum junction temperature is 125°C.
The BQ25713BRSNR has a fixed output voltage option, but it can be configured for a specific output voltage using an external resistor divider network. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
The EN (enable) pin on the BQ25713BRSNR is used to enable or disable the device. When the EN pin is pulled high, the device is enabled, and when it is pulled low, the device is disabled. This pin can be used to implement power sequencing or to turn off the device when not in use.
