The BQ51050BRHLT is a wireless power receiver IC that uses inductive coupling to transfer power wirelessly from the transmitter to the receiver. It is designed for portable devices such as smartphones, tablets and other battery-powered devices.
The device is designed to work with wireless power transmitters that support the Wireless Power Alliance (WPC) Qi 1.2.2 or the Power Affairs Alliance (PMA) Wireless Power standards. It includes an integrated full-bridge rectifier and high efficiency synchronous step-down converter that converts wireless power signals into stable DC voltage to charge the device’s battery.
The BQ51050BRHLT includes built-in protection functions, such as overvoltage protection, overcurrent protection, and thermal protection. These features help ensure the safety and reliability of devices during wireless charging.
The device operates in the high frequency range of 110kHz to 205kHz, enabling efficient power transmission and minimizing interference with other wireless devices. It has a maximum output voltage of 8V and a maximum output current of 1.5A, making it suitable for a wide range of portable devices.
The BQ51050BRHLT also includes a power management unit (PMU) for controlling the wireless power receiver and managing the charging of the device’s battery. Pmus include an I2C interface that allows programmable setup and provides status and fault reporting.
The BQ51050BRHLT comes in a small 20-pin VQFN package with a size of only 4mm x 4mm. It has a wide input voltage range of 4.35V to 19V, making it suitable for a variety of wireless power transmitters.
Overall, the BQ51050BRHLT is a highly integrated and efficient wireless power receiver IC that provides easy wireless charging for portable devices.
