CXES4271 CXES4271A用于外部N沟道MOSFET的高端驱动器允许12V 19V或5V电源导轨错误的输入电压保护功能保护错误的输入适配器插入当输入电压超出目标输入电压范围时IC关闭设备监测VOUT电压以进行短路检测检测到短路

CXES4271 CXES4271A是用于外部N沟道MOSFET的高压侧配电控制器，允许+12V、+19V或+5V电源导轨。错误的输入电压保护功能保护错误的输入适配器插入，当输入电压超出目标输入电压范围时，IC关闭。过电流保护通过使用外部感测电阻器上的电压降来监测输出电流，当输出电流达到触发点时，IC将关闭。CXES4271A CXES4271在通电期间还提供短路保护。该设备监测VOUT电压以进行短路检测，如果检测到短路情况，IC将关闭。其他功能包括指示输出电压已准备好的POK输出和逻辑控制关机模式。

      CXES4271A CXES4271 is a high-side power distribution controller for an external N-channel MOSFET, allow for +12V, +19V or +5V power-supply rail. The wrong input voltage protection function protects a wrong input adapter insertion, when input voltage is out of the target input voltage range the IC is off. The over-current protection monitors the output current by using the voltage drop across the external sensing resistor, when output current reaches the trip point the IC will be shut down. The CXES4271A CXES4271 also provides a shortcircuit protection during power-up. The device monitors VOUT voltages for a short-circuit detection, if a short-circuit condition is detected the IC will be shut down. Other features include a POK output to indicate the output voltage is ready, and a logic-controlled shutdown mode.
