产品简介

CXCL6524过电压保护装置采用低50mW（最大）RON内部FET，保护低压系统免受高达+28VDC的电压故障。内部钳位还可保护器件免受高达+120V的浪涌。当输入电压超过过电压阈值时，内部FET将关闭，以防止损坏受保护的下游元件。过电压保护阈值可以通过可选的外部电阻调整到4V到20V之间的任何电压。当OVLO输入设置低于外部OVLO选择电压时，CXCL6524自动选择准确的内部跳闸阈值。内部过电压阈值（OVLO）预设为15.5V典型（CXCL6524A）、6.8V典型（CXCL6524B）、5.825V典型（CXCL6524C）、9.98V典型（CXCL6524D）和13.32V典型（CXCL6524E）。该器件具有一个开路漏ACOK输出，指示在最小电源电压和VOVLO之间的稳定电源。CXCL6524还通过内部热关机防止过电流事件。

   产品概述 返回TOP

The CXCL6524 overvoltage protection devices feature a low 50mW (max) RON internal FET and protect low-voltage systems against voltage faults up to +28VDC. An internal clamp also protects the devices from surge up to +120V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected downstream components. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V. With the OVLO input set below the external OVLO select voltage, the CXCL6524 automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 15.5V typical(CXCL6524A), 6.8V typical(CXCL6524B),5.825V typical(CXCL6524C),9.98V typical(CXCL6524D), and 13.32V typical(CXCL6524E). The devices feature an open-drain ACOK output indicating a stable supply between minimum supply voltage and VOVLO. The CXCL6524 are also protected against over current events by an internal thermal shutdown.
