General Description
The MAX1693/MAX1694 are current-limited, 60m
switches with built-in fault blanking. Their accurate pre-
set current limit of 0.7A to 1.0A makes them ideally suit-
ed for USB applications. Their low quiescent supply
current (14μA) and shutdown current (1μA) conserve
battery power in portable applications. The MAX1693/
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, an output overcurrent condition caus-
es the switch to current limit at 0.7A to 1.0A and
FAULT
to go low after the 10ms blanking period. When the
overcurrent condition is removed,
FAULT
returns to its
high-impedance state. In the MAX1694, any overcur-
rent 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 thermally
cycling on and off in case of a persistent short-circuit
condition.
The MAX1693/MAX1694 have several safety features to
ensure that the USB port is protected. Built-in thermal-
overload protection limits power dissipation and junc-
tion temperatures. Both devices have accurate internal
current-limiting circuitry to protect the input supply
against overload. They are available in space-saving
10-pin μMAX packages.
