产品概述 返回TOP
The CXUS7728 CXUS7728B CXUS7728C CXUS7728Dseries of power switches are designed for USB applications. The 62mW N-channel MOSFET power switch satisfies the voltage drop requirements of USB specification.The protection features include current-limit protection, short-circuit protection, and over-temperature protection. The device limits the output current at current limit threshold level. When VOUT drops below 1.5V, the devices limit the current to a lower and safe level. The over-temperature protection limits the junction temperature below 140oC in case of short circuit or over load conditions. Other features include a deglitched OCB output to indicate the fault condition and an enable input to enable or disable the device.
