BQ500101 (ACTIVE) NexFET Power Stage

NexFET Power Stage - BQ500101


The bq500101 NexFET Power Stage is optimized for wireless power applications covering the WPC v1.2 medium power specification. The device can be used for both the rail voltage control in fixed frequency transmitter types as well as the coil drivers for both fixed and variable frequency types. This combination produces a high-current, high-efficiency, and high-speed switching device in a small 3.5 × 4.5 mm outline package. In addition, the PCB footprint is optimized to help reduce design time and simplify the completion of the overall system design.
