3 Description

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.
