产品简介
CXPR7882具有低RON内部高压开关和绝对最大30V的输入范围。内部输入箝位能够分流浪涌电压＞80V，保护下游组件并增强系统稳健性。CXPR7882具有过压保护（OVP），当输入电压超过固定的OVP阈值5.85V/10.5V/14.0V时，关闭内部开关。关闭状态开关可以断开输入引脚到输出引脚的连接，并保护输出免受输入高压应力的影响。集成过温保护（OTP）还关闭开关以保护设备。

产品概述 返回TOP
The CXPR7882 features a low RON internal High Voltage Switch and an input range of absolute maximum 30V. An internal input clamp is capable of shunting surge voltage >80V, protecting downstream components and enhancing system robustness. The CXPR7882 features Over-Voltage Protection (OVP) that shuts off the internal Switch if input voltage exceeds the Fixed OVP threshold 5.85V / 10.5V / 14.0V. The off-state Switch can disconnect the input pin to output pin and protect output from the input high voltage stress. Integrated Over-Temperature Protection (OTP) also shuts off the Switch to protect the device.
The CXPR7882 is available in 1.4mm x 1.4mm WLCSP-9B package. Standard product is Pb-free and Halogen-free.
