The uP7558 is a current limited high-side switch designed
for applications where heavy capacitive loads and shortcircuits
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.
The power switch is controlled by a logic enable input and
driven by an internal charge pump circuit. When the output
load exceeds the current-limit threshold or a short is
present, the uP7558 asserts over current protection and
limits the output current to a safe level by driving the power
switch into saturation mode.
