USB Current-Limited Switch
in Pin-Compatible Package
General Description
The MAX1607 is a current-limited 60m Ω switch with
built-in fault blanking. Its accurate, preset 0.7A to 1.0A
current limit makes it ideal for USB applications. Its low
quiescent supply current (14μA) and standby current
(1μA) conserve battery power in portable applications.
The MAX1607 operates with inputs from +2.7V to
+5.5V, making it ideal for both 3V and 5V systems.
An overcurrent signal ( OC ) notifies the microprocessor
that the internal current limit has been reached. A 10ms
overcurrent-blanking 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 blanking also prevents
an OC signal from being issued when the device is
powering up.
The MAX1607 has several safety features to ensure that
the USB port is protected. Built-in thermal-overload pro-
tection limits power dissipation and junction temperature.
The device also has accurate internal current-limiting
circuitry to protect the input supply against overload.
The MAX1607 is a pin-compatible upgrade to Texas
Instruments’ TPS2014, TPS2015, and TPS2041 for USB
applications. The same die is available in a space-sav-
ing 10-pin μMAX ? package (MAX1693) and can be
used for next-generation designs. The MAX1694 is sim-
ilar to the MAX1693, but it has a built-in latch that turns
