具有电流调节功能的 DRV120 单通道继电器、电磁阀、低侧驱动器

DRV120 是一款针对螺线管的 PWM 电流驱动器。 它被设计成使用控制良好的电流来调节电流以确保激活并同时减少功率耗散。 螺线管电流快速斜升以确保阀门或者继电器的打开。 在最初的斜升后，螺线管电流被保持在峰值以确保正确运行，这之后，为了避免过热问题并减少功率耗散，这个电流被减少至较低的保持水平。使用一个外部电容器对峰值电流的持续时间进行设定。 电流斜波峰值和保持电平、以及 PWM 频率可由外部电阻器独立设定。 如果针对相应参数的默认值适用于应用的话，外部设置电阻器也可被省略。 DRV120 可由 6V 至 28V 的外部电源供电运行。 • 用于控制螺线管电流的带有脉宽调制 (PWM) 的集成金属氧化物半导体场效应晶体管 (MOSFET) \n• 螺线管电流的快速斜升以保证激活\n• 可外部设定峰值电流、峰值电流的保持时间、保持电流和 PWM 时钟频率。 它们还可以在无需外部组件的情况下在标称值上运行。\n• 高达 28V 的外部电源电压\n• 保护 \n• 欠压闭锁 (UVLO)\n• 可选状态 (STATUS) 输出\n• 运行温度范围：-40ºC 至 105ºC\n• 8 引脚和 14 引脚 薄型小外形尺寸 (TSSOP) 封装选项;
