DESCRIPTION
CMOS IC
The UTC
US251
is a power distribution switch. It is intended for
applications such as USB where heavy capacitive loads and
short-circuits are likely to be encountered. This family offers
multiple devices with fixed current-limit thresholds for applications
between 0.5A and 2A.
The R
DS(ON)
of the MOSFET switch is as low as 80mΩ. OC is
open-drain output report over-current or over-temperature event
which has deglitch typical 9ms timeout period typically 9ms.
The UTC
US251
incorporates protection circuits including
current limiting circuit with foldback function, thermal shutdown
circuit designed to prevent catastrophic switch failure due to
increasing power dissipation when continuous heavy loads or short
circuit occurs. Besides, a built-in charge pump is used to drive the
N-channel MOSFET that is free of parasitic body diode to eliminate
any reversed current flow across the switch when it is powered off.
The UTC
US251
is applied in high-side power protection switch,
USB power management, USB host and self-powered bubs, USB
bus-powered hubs, hot plug-in power supplies, battery-charger
circuits.
FEATURES
* Single Power Switch Family
