CXES4270是一个用于外部N沟道MOSFET的高压侧配电控制器，允许+12V和+19V供电轨。错误的输入电压保护功能可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，集成电路关闭。内置的欠压保护监视输出电压是否存在短路情况。当输出电压低于车辆识别号电压的70%时，集成电路将关闭。过电流保护通过使用外部MOSFET的RDS（ON）上的电压降来监测输出电流。当输出电流达到触发点时，集成电路将被关闭。CXES4270在通电期间还提供短路保护。该设备监测DRV和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，包括一个POK输出，它指示输出电压已准备就绪和逻辑控制关闭模式。

产品概述 返回TOP
CXES4270 is a high-side power distribution controller for an external N-channel MOSFET, allow for +12V and +19V power-supply rails. 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 built-in under-voltage protection monitors the output voltage for short-circuit conditions. When output voltage is less than 70% of VIN voltage, the IC will be shut down. The over-current protection monitors the output current by using the voltage drop across the external MOSFET’s RDS(ON) . When output current reaches the trip point, the IC will be shut down. The CXES4270 also provides a shortcircuit protection during power-up. The device monitors DRV and VOUT voltages for a short-circuit detection. If a short-circuit condition is detected, the IC will be shut down. Other features, including a POK output which indicates that the output voltage is ready and a logic-controlled shutdown mode.
