3V to 12V Current-Limiting Hot Swap Controllers with Autoretry, DualSpeed/BiLevel Fault Protection

General Description The MAX4271/MAX4272/MAX4273 comprise a complete family of integrated 3V to 12V hot-swap controllers. They allow the safe insertion and removal of circuit cards into live backplanes. Features ♦ Provide Safe Hot Swap for +3V to +12V Power Supplies with Few External Components

3V至12V、限流型、热插拔控制器，带有自动重试以及DualSpeed/BiLevel故障保护

MAX4271/MAX4272/MAX4273包括完整的3V至12V集成热插拔控制器系列。它们支持在带电背板上安全地插拔电路卡。\n\n 电路卡的放电滤波器电容为带电背板提供低阻抗。从背板到电路卡的高浪涌电流会烧毁连接器和元件，或使背板电源瞬间崩溃，导致系统复位。为防止此类问题，该系列的热插拔控制器会在插入电路板时将电流调节到预设限值，从而使系统处于安全的稳定状态。启动周期完成后，两个片内比较器提供DualSpeed/BiLevel™保护，防止短路、负载毛刺和过流状况。在发生故障时，负载会断开连接。故障恢复的处理方式包括解锁(MAX4271)、自动重试(MAX4272)或编程(MAX • 只需很少的外部元件即可为+3V至+12V电源提供安全的热插拔\n\n• 专门设计的电流调节架构大幅缩短了n-FET线性模式持续时间\n\n• 自动重试功能(MAX4272/MAX4273)\n\n• 双速/双级电流限制可防止电流毛刺和短路\n\n• 上电复位(MAX4273)\n\n• 15V的绝对最大额定值可在移除电路板期间防止电感反冲\n\n• 内部电荷泵为外部n-MOSFET产生栅极驱动信号\n\n• 状态输出引脚用于指示故障/安全条件\n\n• 节省空间的8引脚SO、16引脚QSOP封装;
