Infineon Technologies 英飞凌 IFX9201SG 集成型 H 桥驱动器

英飞凌 IFX9201SG 集成型 H 桥驱动器是通用的 6A H 桥驱动器,用于控制小型直流电机和电感负载。可在高达 20kHz 的频率下对输出进行脉宽调制。这使操作频率超出人耳能听到的声波频率范围- 通过 PWM/DIR 控制。方向输出处的信号界定了直流电机的方向,而 PWM 信号控制着占空比。对于超出电流限制阈值(典型值为 7A)的负载电流,H 桥驱动器切换成斩波限流模式。该器件针对短路和过温状态提供保护,并通过 SPI 提供分析功能或通过状态标志提供基本错误反馈。当桥接器被禁用或在对电感负载进行脉宽调制时,可检测到开路负载。

For load currents above the current limitation threshold (7A typ.) the H-Bridge switches into chopper current limitation mode. The device is protected against short circuits and over temperature and provides diagnosis via SPI or basic error feedback via status flag. Open load can be detected when the bridge is disabled or during PWM operation of inductive loads.
