BQ24190RGER 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 can be configured for various charging profiles, such as constant current, constant voltage, or trickle charge, by adjusting the ISET and VREG pins accordingly.
  • The device has a thermal shutdown feature that turns it off when the junction temperature exceeds 150°C. Ensure good airflow, use a heat sink if necessary, and avoid overheating the device to ensure reliable operation.
