BQ24002PWPR Frequently Asked Questions (FAQs)
The recommended layout and placement for the BQ24002PWPR involves placing the device close to the battery, using a solid ground plane, and keeping the input and output capacitors close to the device. A 4-layer PCB with a solid ground plane is recommended. TI provides a reference design and layout guidelines in the datasheet and application notes.
The BQ24002PWPR has a programmable charging current and voltage. To optimize the charging current and voltage for your specific battery, you can use the ISET pin to set the charging current and the VREG pin to set the charging voltage. You can also use external resistors to adjust the charging current and voltage. Refer to the datasheet and application notes for more information.
The BQ24002PWPR has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. To ensure reliable operation, it's essential to provide adequate thermal dissipation, such as using a heat sink or a thermal pad, and to follow the recommended PCB layout guidelines.
The BQ24002PWPR has a built-in overcharge protection feature that can be enabled by connecting the OVP pin to a voltage source. You can also use external components, such as a voltage supervisor, to implement overcharge protection. Refer to the datasheet and application notes for more information.
The BQ24002PWPR is designed to meet EMI and EMC standards, but it's essential to follow proper PCB layout and design guidelines to minimize EMI and ensure EMC compliance. Use a shielded cable for the input and output, and follow the recommended layout guidelines to minimize radiation.
