US201-AF5-R(2009) Datasheet PDF - Unisonic Technologies

DESCRIPTION
The UTC US201/A series are 80mΩ, 500mA for US201 (1.1A for US201A) high-side power switches. There’s internal single low voltage N-Channel MOSFET which makes it an ideal for all USB applications. This MOSFET should be driven by a charge pump circuitry inside. Its switch on resistance is as low as 80mΩ which we know specially meets the drop voltage for USB applications.

FEATURES
* 80mΩ(typ) N-Channel MOSFET
* Supply current:
    – Switch on :25μA(typ)
    – Switch off :1μA (typ)
* Load current 500mA for US201 and 1.1A for US201A
* Input voltage from 2V to 5.5V
* In off-state: Output voltage can be higher than input
