TPS22975 米6体育平台手机版_好二三四系列包含两个器件:TPS22975 和 TPS22975N。每个器件都是一款单通道负载开关,可提供可配置的上升时间来尽量减小浪涌电流。此器件包括一个 N 通道金属氧化物半导体场效应晶体管 (MOSFET),可在 0.6 V 至 5.7V 的输入电压范围内运行并可支持 6A 的最大持续电流。此开关由一个开/关输入 (ON) 控制,此输入能够直接连接低电压控制信号。TPS22975 包含一个可选 230Ω 片上负载电阻,用于在此开关关断时进行快速输出放电。
TPS22975 采用小型,节省空间的 2mm × 2mm 8 引脚 SON 封装 (DSG),集成的散热焊盘允许该器件产生较高的功率耗散。该器件在自然通风环境下的额定运行温度范围为 –40°C 至 +105°C。
