BQ51051BRHLR

The BQ51051BRHLR from Texas Instruments is a high-efficiency, Qi-compliant wireless power receiver with an integrated battery charge controller, designed for portable applications. This device efficiently converts AC power to DC, integrating the digital controller required for the Qi v1.2 communication protocol and providing essential algorithms for safe and efficient Li-Ion and Li-Pol battery charging.

Key electrical specifications include an operating temperature range of 0°C to 125°C, an input voltage range of 4V to 10V, and a quiescent current of 8mA. It supports a charging current up to 1.5A with a peak AC-DC charging efficiency of 93%. The device also features a maximum input voltage tolerance of 20V with overvoltage protection, thermal shutdown, and overcurrent protection.

Packaged in a compact 20-VQFN (3.5x4.5 mm) with an exposed pad, the BQ51051BRHLR is suitable for space-constrained designs. It combines a wireless power receiver, rectifier, and battery charger into a single, small package, enabling direct battery charger solutions when paired with a compatible transmitter-side controller.

This component is designed for applications requiring wireless power transfer, such as smartphones, wearables, and other portable electronic devices. Its robust architecture and compliance with industry standards make it a reliable choice for wireless charging solutions.
