Silicon Labs Si823x 隔离驱动器
Silicon Labs Si823x 隔离驱动器在一个封装中集成了两个独立的隔离驱动器。Si8230/1/3/4 为高侧/低侧驱动器，而 Si8232/5/6/7/8 为双驱动器。这些驱动器具有 0.5A（Si8230/1/2/7）和 4.0A（Si8233/4/5/6/8）的峰值输出电流。所有驱动器的最大供电电压为 24V。Si823x 驱动器采用 Silicon Labs 的专利硅隔离技术，提供符合 UL1577 的 5 kVRMS 耐受电压以及 60 ns 的快速传送时间。驱动器输出可连接到相同或独立的地线进行接地，或连接到正或负电压。单个控制输入（Si8230/2/3/5/6/7/8）或 PWM 输入（Si8231/4）配置提供滞后 >400 mV 的 TTL 级兼容输入。高度的集成、低传送延迟、较小的外形及其灵活性和成本效益使 Si823x 系列非常适合 MOSFET/IGBT 门驱动隔离应用。
The outputs of the Si823x Isolated Drivers can be grounded to the same or separate grounds or connected to a positive or negative voltage. The TTL level compatible inputs with >400mV hysteresis are available in individual control input (Si8230/2/3/5/6/7/8/9) or PWM input (Si8231/4) configurations. High integration, low propagation delay, small installed size, flexibility, and cost-effectiveness make the Si823x family ideal for a wide range of isolated MOSFET/IGBT gate drive applications.
