USB Current-Limited Switches
with Fault Blanking
General Description
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.
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.
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.
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.
