产品概述 返回TOP
The CXPR7881D is an Over-Voltage-Protection (OVP) and Over-Current-Protection (OCP) device. The device will switch off internal MOSFET to disconnect VIN to VOUT to protect load when any of input voltage, input current over the threshold. The over temperature protection (OTP) function monitors chip temperature to protect the device.
The CXPR7881D is available in DFN2x2-6L package. Standard products are Pb-free and Halogen-free.
