BQ500101屬于集成電路（IC）的全半橋驅動器。由美國德州儀器公司制造生產的BQ500101全半橋驅動器器件屬于電橋驅動器電源管理集成電路 (PMIC) 系列，包含兩個或多個功率晶體管，以及在外部器件控制下將其用作開關所需的電路。這些晶體管通常在內部配置為成對串聯(lián)連接（稱為半橋），因而任意指定晶體管對之間的結點都可以連接至兩個電源軌中的任一個。這類器件常用于將控制器件（如微控制器）提供的低電平信號轉換為操作執(zhí)行器（如步進電機或無刷電機）所需的較大功率信號。

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.
