Microchip Technology MCP8024栅极驱动器
Microchip MCP8024是带电源模块的三相无刷直流(BLDC)栅极驱动器。MCP8024器件集成了三个用于驱动外部NMOS/NMOS晶体管对(晶体管对配置为驱动三相BLDC 电机)的半桥驱动器、一个比较器、一个用于为配套微控制器提供偏置的稳压器、若干功率监视比较器、一个超温传感器、两个电平转换器和三个用于监视电机电流的运算放大器。MCP8024具有三个半桥驱动器,可在12V时提供0.5A的峰值输出电流来驱动高边和低边NMOS MOSFET晶体管。该驱动器具有直通、过流和短路保护。MCP8024降压转换器可提供750mW的功率,为配套微控制器供电。如果不使用降压稳压器,可禁用它。板载5V和12V低压差稳压器可提供20mA的电流。MCP8024额定工作于40℃到+150℃的温度范围。有40引脚5x5 QFN和48引脚7x7 TQFP封装可选。特性
