TI公司的DRV832x系列是带三个电流分流放大器的6-60V三相智能栅极驱动器.器件集成了三个独立的半桥栅极驱动器,电荷泵,用于高边和低边栅驱动的线性稳压器以及三个电流分流放大器和600mA降压稳压器,从而降低系统元件数量,成本和复杂性.标准串行外设接口(SPI)提供简便方法来配置各种参数设定和故障诊断信息.主要用在BLDC马达模块,CPAP,风扇和泵,电动自行车,电动工具和无人机,机器人和RC玩具以及ATM和点钞机.本文介绍了DRV832x系列主要特性,多种器件功能框图,以及三相无刷DC(BLDC)马达1kW功率级参考设计TIDA-00774主要特性,框图,电路图,材料清单和PCB设计图.
The DRV832x family of devices are integrated 6 to 60-V gate drivers for three-phase motor drive applications.These devices reduce system component count, cost, and complexity by integrating three independent halfbridgegate drivers, charge pump and linear regulator for the high-side and low-side gate driver supply voltages,optional triple current shunt amplifiers, and an optional 600-mA buck regulator. A standard serial peripheralinterface (SPI) provides a simple method for configuring the various device settings and reading fault diagnostic information through an external controller. Alternatively, a hardware interface (H/W) option allows for configuringthe most commonly used settings through fixed external resistors.
