BQ500414Q - Automotive Qi Wireless Power Controller | Texas Instruments
MPN: BQ500414Q ✓ Hoạt độngBQ500414Q Tóm tắt
What is a wireless power controller? A wireless power transmitter controller is a specialized power management IC that manages the power transfer between a transmitter and a receiver using inductive coupling. It coordinates the coil switching, modulates the power signal, and communicates with the receiver through the Qi protocol to ensure safe and efficient charging. The BQ500414Q simplifies designs by integrating the control logic, I2C interface, and LED drive outputs, reducing the external component count and system complexity.
Key features of the BQ500414Q include direct driving of three LED outputs through pins 7, 8, and 9 using a simple current-limit resistor (typically 470 ohms), which provides visual status indication without additional driver ICs. The I2C interface enables communication with host controllers, allowing system-level monitoring and configuration. The free-positioning capability of the controller supports multi-coil arrangements, enabling convenient placement of receivers on the charging surface.
The BQ500414Q is designed for automotive applications where robustness and reliability are critical. Its AEC-Q100 qualification ensures it meets stringent automotive quality standards. The device is WPC v1.1 ready, conforming to the Qi wireless charging standard for interoperability with compliant receivers. The transmitter type A6 specification defines the coil geometry and power transfer characteristics, and the controller is optimized for 12-V systems, which are common in automotive power architectures.
Typical applications include in-cabin wireless phone chargers, aftermarket charging pads, and industrial or medical devices requiring wireless power. The device's EEPROM-programmable parameters allow customization for specific system requirements, and the integrated LED drivers simplify user feedback. When designing with this controller, pay careful attention to the thermal management of the power stage and the layout of the coil driver circuitry, as these directly influence charging efficiency and EMI performance.

Ghi chú thiết kế
The BQ500414Q is optimized for 12-V supply systems. Ensure the input voltage remains within the recommended operating range to prevent malfunction. Use a robust power supply with adequate current capability for the transmitter coil driver. Consider adding a TVS diode on the supply line to protect against automotive load dumps and transients.
Even though the controller itself consumes low power, the power stage driving the coil can dissipate significant heat. Design the PCB with adequate copper pour and thermal vias under the power components. Ensure the VQFN-48 package's exposed pad is soldered to a large ground plane for effective heat spreading, especially in high-ambient automotive environments.
For EMI compliance, keep the coil driver traces short and route them with a ground plane underneath. Place decoupling capacitors close to the controller's power pins. The LED outputs on pins 7, 8, 9 can be driven with a 470-ohm series resistor; route these traces away from analog sensing areas to avoid noise coupling.
