产品概述 返回TOP
The CXUS7729A CXUS7729B CXUS7729C CXUS7729D series of power switches are designed for USB applications. The 70mW 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, and when VOUT drops below 1.5V, the devices limit the current to a lower and safe level. The OTP limits the junction temperature below 140oC in case of short circuit or over load conditions. Other features include deglitched OCBx output to indicate the fault condition and ENx input to turn on or turn off output.
