MAX1607ESA
USB Current-Limited Switch in Pin-Compatible Package
General DescriptionThe MAX1607 is a current-limited 60mΩswitch 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 OCsignal 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 tempera-
ture. 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-saving
10-pin μMAX package (MAX1693) and can be used for
next-generation designs. The MAX1694 is similar to the
MAX1693, but it has a built-in latch that turns off the
power switch in case of a long-term short-circuit condi-
tion.

MAX1607
USB Current-Limited Switch
in Pin-Compatible Package
Detailed DescriptionThe MAX1607 P-channel MOSFET power switch limits
output current to 0.7A min and 1.0A max. When the out-
putcurrent is increased beyond the current limit (ILIMIT),
the current also increases through the replica switch
(IOUT/ 6500). The current-limit error amplifier compares
the voltage to the internal 1.24V reference and regu-
lates the current back to the ILIMIT(Figure 1).
These switches are not bidirectional; therefore, the
input voltage must be higher than the output voltage.
Continuous Short-Circuit ProtectionThe MAX1607 is a short-circuit-protected switch. In the
event of an output short-circuit condition, the current
through the switch is foldback-current-limited to 500mA
continuous.
Thermal ShutdownThe MAX1607 has a thermal shutdown feature. The
switch turns off and the OCoutput goes low immediate-
ly (no overcurrent blanking) when the junction tempera-
ture exceeds +165°C. When the MAX1607 cools 20°C,
the switch turns back on. If the fault short-circuit condi-
tion is not removed, the switch will cycle on and off,
resulting in a pulsed output.
IndicatorThe MAX1607 provides an overcurrent output (OC). A
100kΩpull-up resistor from OCto IN provides a logic
control signal. This open-drain output goes low when
any of the following conditions occur: The input voltage is below the 2.4V undervoltage-
lockout (UVLO) threshold.The die temperature exceeds the thermal shutdown
temperature limit of +165°C.The device is in current limit for greater than 10ms.
OC BlankingThe MAX1607 features 10ms overcurrent blanking.
Blanking allows brief current-limit faults, including
momentary short-circuit faults that occur when hot-
swapping a capacitive load, and also ensures that nois issued during power-up. When a load transient
causes the device to enter current limit, an internal
counter starts. If the load fault persists beyond the
10ms overcurrent-blanking timeout, the OCoutput
asserts low. Ensure that the MAX1607 input is ade-
quately bypassed to prevent input glitches from trigger-
ing spurious OCoutputs. Input voltage glitches less
