MAX1562ESA-MAX1562HESA
Programmable 4A USB Current-Limited Switches with Autoreset and Fault Blanking
General DescriptionThe MAX1562/MAX1562H/MAX1563 single current-
limited switches provide up to 4A to power up to eight
USB ports. They operate from a 4V to 5.5V input
supply and consume only 40µA of quiescent current
when operating and only 3µA in shutdown.
The MAX1562/MAX1562H/MAX1563s’ autoreset feature
latches the switch off if the output is shorted, thereby
saving system power. When the short is removed, the
switch is reactivated. A fault-blanking feature enables the
circuit to ignore momentary faults, such as those caused
when hot swapping a capacitive load, preventing false
alarms to the host system. Fault blanking also prevents
fault signals from being issued when the device powers
up the load.
The MAX1562/MAX1562H/MAX1563 provide several
safety features to protect the USB port. Built-in thermal-
overload protection turns off the switch when the die
temperature exceeds +160°C. Accurate internal cur-
rent-limiting circuitry protects the input supply against
both overload and short-circuit conditions. An open-
drain fault signal (FAULT) notifies the microprocessor
when a thermal-overload, current-limit, undervoltage
lockout (UVLO), or short-circuit fault occurs.
The MAX1562 has an active-low ON, and the
MAX1562H has an active-high ON enable input. The
MAX1563 has a selectable active-high or active-low
logic-controlled enable. The current limit is pro-
grammed from 1A to 4A using a resistor.
The MAX1562/MAX1562H are available in 8-pin SO
packages and are pin-compatible upgrades to the
MIC2545A/MIC2549A. The MAX1563 provides the
same features and higher current performance in a
smaller 12-pin (4mm x 4mm) QFN package. These
devices operate over an extended temperature range
(-40°C to +85°C). An evaluation kit is available to speed
designs.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
