BA5916集成电路（IC）的全半桥驱动器规格书PDF中文资料

BA5916属于集成电路（IC）的全半桥驱动器。由罗姆半导体集团制造生产的BA5916全半桥驱动器器件属于电桥驱动器电源管理集成电路 (PMIC) 系列，包含两个或多个功率晶体管，以及在外部器件控制下将其用作开关所需的电路。这些晶体管通常在内部配置为成对串联连接（称为半桥），因而任意指定晶体管对之间的结点都可以连接至两个电源轨中的任一个。这类器件常用于将控制器件（如微控制器）提供的低电平信号转换为操作执行器（如步进电机或无刷电机）所需的较大功率信号。

The BA5970FP is a 4-channel BTL driver developed to drive CD player motors and actuators. The driver input stage contains an operational amplifier, supports a variety of input formats, and allows simple configuration of a filter.

特性 Features

1) 4-channel BTL driver.

2) Wide dynamic range (4V when PREVCC = 8V, POWVCC = 5V, and RL = 8Ω).

3) Internal thermal shutdown circuit.

4) Driver gain is adjustable with externally connected resistor.

5) Independent power supplies PREVCC, POWVCC (for channels 1 and 2), and POWVCC (for channels 3 and

4), and low voltage operation for a highly efficient drive.

6) Independent mute pins for channels 1 and 2 and channels 3 and 4.

7) Perfect for compact applications with the use of the HSOP28-pin power package.

Applications

CD players, CD-ROM
