UNISONIC TECHNOLOGIES CO.
, LTD US251 CURRENT-LIMITED, POWER-DISTRIBUTION SWITCHES  DESCRIPTION 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 RDS(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 t...
