BQ24002PWP Frequently Asked Questions (FAQs)

  • A good layout practice is to keep the input and output capacitors close to the IC, and to use a solid ground plane to reduce noise and EMI. Additionally, it is recommended to keep the high-current paths (e.g. from the input capacitor to the IC) short and wide to reduce resistance and inductance.
  • The input capacitor should be a low-ESR ceramic capacitor with a value of at least 10uF, and the output capacitor should be a low-ESR ceramic capacitor with a value of at least 22uF. The capacitor values and types should be chosen based on the specific application requirements and the output voltage ripple and noise requirements.
  • The BQ24002PWP can handle input voltages up to 18V, but it is recommended to keep the input voltage below 15V to ensure reliable operation and to prevent overheating.
  • The charge current and voltage of the BQ24002PWP can be programmed using external resistors connected to the ISET and VSET pins, respectively. The values of these resistors determine the charge current and voltage, and can be calculated using the equations provided in the datasheet.
  • The EN pin is an active-high enable input that allows the user to turn the charger on and off. When the EN pin is high, the charger is enabled, and when it is low, the charger is disabled. This pin can be used to control the charger using a microcontroller or other external logic.
