Texas Instruments DRV8313三路半H桥驱动器
德州仪器DRV8313三路半H桥驱动器 具有三个能够独立控制的半H桥驱动器。它既可用于驱动三相无刷直流电机，同时也可用于驱动螺线管或其他负载。每个输出驱动器通道都包括半H桥配置的N通道功率MOSFET。这种设计将每个驱动器的接地端子带到引脚上，因此，用户可对每个输出执行电流感测。通用比较器还可用于限流电路或其他功能。DRV8313可在每半H桥提供每通道高达2.5A峰值或1.75A RMS输出电流（在24V和25℃条件下采用适当的PCB散热措施）。这款器件可为过流保护、短路保护、欠压闭锁、 温度过高时提供内部关断功能。DRV8313采用28引脚HTSSOP PowerPAD封装。
