快速瞬态响应CXPR78104过电压保护OVP集成电路超低30mΩ RDSON大电流高压MOSEFT维持高达32V直流电压保护下游设备免受高压浪涌

CXPR78104是一种过电压保护（OVP）集成电路，具有超低30 mΩRDSON大电流高压MOSEFT。它可以维持高达32V直流电压，保护下游设备免受高压浪涌。当CXPR78104的输入电压超过OVP阈值时，它会快速响应并关闭MOSFET。OVP阈值可通过电阻进行外部调节。开关的内部设置电流限制也高达5.5A。当过载情况发生时，它进入打嗝模式，以保护集成电路不过热。它还具有过热保护功能，关闭MOSFET。CXPR78104在CSP3X4包中提供。

      CXPR78104 is an Over-Voltage-Protection (OVP) IC with an ultralow 30 mΩ RDSON high current high voltage MOSEFT. It can sustain voltage as high as 32V DC, protecting downstream devices from high voltage surges. When input voltage of CXPR78104 exceed the OVP threshold, it responses quickly and shuts off the MOSFET. The OVP threshold is externally adjustable with resistors. There is also an internally set current limit up to 5.5A for the switch. When overload condition occurs, it goes into a hiccup mode to protect the IC from over-heating. It also has an overtemperature protection feature that turns off the MOSFET. CXPR78104 is available in CSP3X4 package.
