US251 - POWER-DISTRIBUTION SWITCHES

General 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.

Key Features

  • Single Power Switch Family.
  • 80-mΩ High-Side MOSFET.
  • Rated currents of 0.5 A, 1 A, 1.5 A, 2 A.
  • Accurate, Fixed, Constant Current Limit.
  • Deglitched Fault Reporting.
  • Output Discharge When Disabled.
  • Reverse Current Blocking.
  • Built-in Softstart.

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.
