US2175 Datasheet

DUAL USB HIGH-SIDE POWER SWITCH


 
DESCRIPTION
 
The US2175 is a high-side power switch with two channels. It
particularly designed for the Universal Serial Bus (USB) including
self-powered and bus-powered types. The RDS(ON) of the MOSFET
switch is as low as 110mΩ.
The US2175 incorporates protective functions, such as
overcurrent protection, thermal shutdown and UVLO (UnderVoltage
Lockout) protection circuits. The thermal shutdown function provides
individual control for each switch. An open-drain fault flag playing a
role as the output of an N-channel is also included. Once any error
occurs the fault flag will be in active.
The US2175 can be applied in hot plug in power supplies and
battery charger circuits as well.
 


FEATURES

* On-State Supply Current: 65μA (TYP.)
* Off-State Supply Current:.1μA (TYP.)
* Current-Limit / Short Circuit Protection and Thermal Shutdown Protection Under Overcurrent Condition
* UVLO Makes the Switch OFF at Start UP
* With Slow Turn ON and Fast Turn OFF
* Enable Active-Low or Active-High
* Halogen Free
