Current-Limited, Power Distribution Switches
General Description
Features
The uP7534 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 (25uA) and standby 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 uP7534 asserts overcurrent protection and
limits the output current to a safe level by driving the power
switch into saturation mode.
The uP7534 features glitch-blank fault flag that is asserted
by overcurrent, overtemperature, or input undervoltage
lockout. 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. The uP7534 is available in
SOP-8 , SOT23-5, MSOP-8, and PMSOP-8 packages.
