The TPS22969 is a small, ultra-low RON, single channel load
switch with controlled turn on. The device contains an N-channel MOSFET that can operate over an
input voltage range of 0.8 V to 5.5 V and can support a maximum continuous
current of 6 A.
The combination of ultra-low RON and high current capability of the device makes it ideal for driving processor rails with very tight voltage dropout tolerances. The controlled rise time of the device greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating voltage droop on the power supply. The switch can be independently controlled via the ON pin, which is capable of interfacing directly with low-voltage control signals originating from microcontrollers or low voltage discrete logic. The device further reduces the total solution size by integrating a 224-Ω pull-down resistor for quick output discharge (QOD) when the switch is turned off.
The TPS22969 is available in a small 3.00 mm x 3.00 mm SON-8 package (DNY). The DNY package integrates a thermal pad which allows for high power dissipation in high current and high temperature applications. The device is characterized for operation over the free-air temperature range of –40°C to 105°C.

TIDM-WLMOTORMONITOR — 无线电机监控器参考设计
该参考设计的灵感来自需要监测电机和机器的运行状况，以准确预测和安排维护（或更换），同时更大限度地减少工业生产期间的成本和停机。目前，数以百万计的工业电机通过手持或有线压电加速度计传感设备进行监测。超低功耗处理技术、无线电和压电传感器小型化的最新进展使得具有无线功能的低成本小型电机监测器的开发和部署成为可能。这些无线电机监测器由纽扣电池供电，电池寿命超过 10 年。这些系统提供与现有手持系统相同的宽带灵敏度，收集振动数据并对该数据进行光谱分析。这种集成智能让您可以在难以进入的位置部署和监测这些系统。无线电机监测参考设计使用两种不同但电气等效的外形进行开发和测试。
这些外形包括：
- 模块化外形
- 紧凑外形
