NXP Semiconductors 恩智浦 NX5P 高端电源开关

恩智浦 NX5P 逻辑控制型高侧电源开关是一款功能丰富的智能负载开关，用于电源管理。NX5P 开关可保护脆弱的 USB 附件免受电压和电流瞬变的影响，提供电源隔离，通过 LDO 解决方案降低功耗，并延长电池使用寿命。

NXP Load Switches integrate reverse voltage protection, over-voltage protection, over-current protection, and over-temperature protection. These protection features prevent damage to the load switch and the components it supplies when a system fail event is detected. Integrated slew-rate control reduces the inrush current when supplying a sub-system.

特性

Wide input voltage range of 1.1V to 20V for design flexibility
Low R_ON of 20mΩ (typical) for low loss across the switch
Overvoltage tolerant threshold control logic eliminates external level shifters
Integrated resistor to discharge load capacitance when the switch is disabled

Reverse voltage protection
Low power off-leakage current for extended battery life
Under-voltage lockout ensures the switch remains disabled when a voltage less than the operating range is applied
Over-temperature shutdown prevents any damage to switch and downstream peripherals
