BTS7960P集成电路（IC）的全半桥驱动器规格书PDF中文资料

BTS7960P属于集成电路（IC）的全半桥驱动器。由英飞凌科技股份公司制造生产的BTS7960P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。

Overview

The BTS 7960is part of the NovalithICfamily containing three separate chips in one package: One p-channel highside MOSFET and one n-channel lowside MOSFET together with a driver IC, forming a fully integrated high current half-bridge. All three chips are mounted on one common leadframe, using the chip on chip and chip by chip technology. The power switches utilize vertical MOS technologies to ensure optimum on state resistance. Due to the p-channel highside switch the need for a charge pump is eliminated thus minimizing EMI. Interfacing to a microcontroller is made easy by the integrated driver IC which features logic level inputs, diagnosis with current sense, slew rate adjustment, dead time generation and protection against overtemperature,

overvoltage, undervoltage, overcurrent and short circuit. The BTS 7960 can be combined with other BTS 7960 to form H-bridge and 3-phase drive configurations.
