A good PCB layout for the BQ24093DGQR involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces between the device and the capacitors. TI provides a recommended PCB layout in the datasheet and application notes.
The selection of external components such as capacitors, resistors, and inductors depends on the specific application requirements. TI provides guidelines for component selection in the datasheet and application notes. Additionally, TI's WEBENCH online design tool can be used to select components and simulate the design.
The BQ24093DGQR has a thermal pad that must be connected to a solid ground plane to ensure proper heat dissipation. The device can operate up to 105°C, but the junction temperature should be kept below 125°C to ensure reliability. A thermal analysis should be performed to ensure the device operates within the recommended temperature range.
Troubleshooting the BQ24093DGQR involves checking the input voltage, output voltage, and current. Verify that the device is properly configured and that the external components are correctly selected. Use an oscilloscope to check for voltage and current waveforms. TI's application notes and technical support resources can also be used to troubleshoot issues.
The BQ24093DGQR is a switching regulator that can generate electromagnetic interference (EMI). To minimize EMI, use a shielded inductor, keep the layout compact, and use a common-mode choke. Additionally, follow TI's guidelines for EMI reduction in the datasheet and application notes.
