BQ24195RGER Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. Keep the input and output capacitors close to the IC, and use a Kelvin connection for the sense resistors.
  • Choose a sense resistor value that sets the current limit to the desired value. A lower sense resistor value will result in a higher current limit. Use the formula: Rsense = 0.05 / Ilim, where Ilim is the desired current limit in amps.
  • The EN pin is an active-high enable input that allows the device to be turned on and off. Connect EN to a logic high (e.g., VCC) to enable the device, and connect it to a logic low (e.g., GND) to disable it.
  • Use the ISET pin to set the charge current, and the VREG pin to set the output voltage. The device also has a built-in thermal regulation feature that reduces the charge current when the device temperature exceeds 120°C.
  • The device has a thermal shutdown feature that turns off the device when the junction temperature exceeds 150°C. Ensure good airflow, use a heat sink if necessary, and follow the recommended PCB layout to minimize thermal resistance.
