Power switches increase power density in USB port protection
The latest family of current limited power switches from Diodes is designed to enable power density to be increased in the protection of multiple USB 3.0 ports used in applications such as set top boxes, led tvs and notebook computers.
The six new single channel devices are available in an ultra small (2 x 2mm) DFN2020-6 package, have an on resistance of 70mO and cover maximum continuous output currents up to 2.5A.
For applications subject to heavy capacitive loads and a possibility of short circuit, Diodes says the switches provide a robust port protection solution, comprising reverse current blocking, over current, over temperature, under voltage lockout and short circuit protection.
All devices also integrate an output discharge function to ensure controlled discharging of the output capacitor. In addition, the switches' fast short circuit response time of 2µs prevents any unnecessary system shutdown or restart.
