QW-R502-609.A

100mΩ, 2A SLEW RATE

CONTROLLED LOAD SWITCH

DESCRIPTION

The UTC US205 is a cost-effective, low-voltage, low switch-on

resistance (typ. 100mΩ) high-side Power Switch IC. It has a 20μA

low quiescent supply current that meets the requirements of

battery-powered portable equipment.

The UTC US205 incorporates protection circuits, such as an

over-current protection circuit, a short fold back circuit, a thermal

shutdown circuit and an under-voltage lockout circuit for overall

protection. Besides, a slew rate controlled function is embedded for

turn-on rising time control.

The UTC US205 can be usedin applications, such as Cellular

Phones, Digital still Camera, Hot swap Supplies, Notebook

Computers, Personal Communication Devices, Personal Digital

Assistants and so on.

The UTC US205 is available in SOP-8 package.
