USB Current-Limited Switches  
with Fault Blanking  
General Description  
Features  
The MAX1693/(MAX1693H)/MAX1694 are current-limit-  
ed, 60mΩ switches with built-in fault blanking. Their  
accurate preset current limit of 0.7A to 1.0A makes them  
ideally suited for USB applications. Their low quiescent  
supply current (14µA) and shutdown current (1µA) con-  
serve battery power in portable applications. The  
MAX1693/(MAX1693H)/MAX1694 operate with inputs  
from 2.7V to 5.5V, making them ideal for both 3V and 5V  
systems.  
o Accurate Current Limit (0.7A min, 1.0A max)  
o Guaranteed 0.75A Short-Circuit Protection  
o 10ms Internal Fault-Blanking Timeout  
o No Fault Signal During Power-Up  
o Latched FAULT Output Turns Off Power Switch  
(MAX1694)  
o Thermal Shutdown Protection  
o 2.7V to 5.5V Supply Range  
o 14µA Supply Current  
A fault signal notifies the microprocessor that the inter-  
nal current limit has been reached. A 10ms fault-blank-  
ing feature allows momentary faults (such as those  
caused when hot-swapping into a capacitive load) to be  
ignored, thus preventing false alarms to the host system.  
This fault blanking also prevents a fault signal from  
being issued when the device is powering up.  
o Small 10-Pin µMAX Package  
o UL Recognized–#E211935  
In the MAX1693/(MAX1693H), an output overcurrent  
condition causes the switch to current limit at 0.7A to  
1.0A and FAULT to go low after the 10ms blanking peri-  
od. When the overcurrent condition is removed, FAULT  
returns to its high-impedance state. In the MAX1694,  
any overcurrent longer than 10ms will latch the switch  
open and set FAULT low. The latch is cleared by cycling  
the ON input or by powering up the device again. This  
feature saves power by preventing the device from ther-  
mally cycling on and off in case of a persistent short-cir-  
cuit condition.  
Applications  
USB Ports and Hubs  
Notebook Computers  
Portable Equipment  
Docking Stations  
Hot Plug-In Power Supplies  
Battery-Charger Circuits  
Ordering Information  
The MAX1693/(MAX1693H)/MAX1694 have several  
safety features to ensure that the USB port is protected.  
Built-in thermal-overload protection limits power dissi-  
pation and junction temperatures. All devices have  
accurate internal current-limiting circuitry to protect the  
input supply against overload. They are available in  
space-saving 10-pin µMAX packages.
