LM3543-三重端口USB配电开关和过电流保护
LM3543是一个三层高侧电源开关，是一个很好的选择，使用根，自供电和总线供电的USB（通用串行总线）集线器。独立端口允许，标志信号，提醒的USB控制器错误的条件下，启动控制的热插拔事件，并短路保护所有符合USB规范要求。LM3543接受2.7V和5.5V之间的输入电压。使能逻辑输入，可在高有效有源低版本的，可以在断电的任何电压2.7V至5.5V的范围内。连续的LM3543限制电流通过一个单一的端口，以1.25A（最大）时，接地短路。LM3543开关低通态电阻，确保LM3543将满足USB的电压降的要求，即使当电流通过交换机达到500 mA的。因此，高功率的USB功能，低功率的USB功能，总线
