Texas Instruments TPS229xx 5.5V 2A 负载开关
德州仪器 TPS229xx 5.5V 2A 负载开关是一款小型、低导通电阻、单通道负载开关，具有受控压摆率。每一器件均包括一个 N-通道 MOSFET，可在 1.05V 至 5.5V 的输入电压范围下工作，并支持最高达 2A 的持续电流。这款开关通过开/关输入控制，该输入能够直接对接低压控制信号。小尺寸、低导通电阻特性 使得这些器件适合用于狭小空间内由电池供电的应用。这款开关的宽幅输入电压范围使其成为许多电压轨的多功能解决方案。这些器件受控的上升时间大大减少了大容量负载电容引起的冲击电流，从而减少或消除了电源供应下降的现象。TPS22915 通过集成一个用于开关关上之时快速输出放电(QOD)的 143Ω 下拉电阻，进一步减小了总解决方案尺寸。
The small size and low RON of the TPS229xx Load Switches make them ideal for use in space constrained, battery-powered applications. The wide input voltage range of the switches makes them a versatile solution for many different voltage rails. The controlled rise time of these devices greatly reduces inrush current caused by large bulk load capacitances, thereby reducing or eliminating power supply droop. Certain TPS229xx Load Switches further reduce the total solution size by integrating a pull-down resistor for quick output discharge (QOD) when the switch is turned off.
