uP7534
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.

Pin Name Pin Function
OC#
Fault Flag. This is an active-low, open-drain fault flag output for p the power switch. The uP7534
asserts this pin low when fault occurs with typical 8ms deglitching time delay.
VOUT
Output Voltage. These pins are output from N-Channel MOSFET Source. Bypass this pin with a
minimum 10uF capacitor to ground.
GND Ground.
EN/EN#
Enable Input. This is the enable input to turn on/off the power switch. Active high for uP7534A/C/E/G
and active low for uP7534B/D/F/H
VIN
Supply Input. This is the input pin to N-Channel MOSFET Drain and supply to control circuit. Bypass
this pin with a 22uF capacitor to ground.
NC Not Internally Connected.
