General Description

The uP7558T/U is a current limited high-side switch designed for applications where heavy capacitive loads and short-circuits are likely to be met.

This device operates with inputs from 2.7V to 5.5V for both 3V and 5V systems.

Its low quiescent current and shutdown current(<1uA) conserve battery power in portable.

Overview

uP7558T/U Current-Limited, Power Distribution Switches General.

Key Features

  • glitch-blank fault flag that is asserted by over current and over temperature. The 8ms glitch-blanking time allows momentary faults to be ignored, thus preventing false alarms to the host system. Other features include soft-start to limit inrush current during plug-in, thermal shutdown to prevent catastrophic switch failure from high-current loads, under-voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, and output reverse voltage to turn.
