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.
