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

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.
